I'm looking for some nice 4AA flashlights.
So far I only have a Jetbeam PA40.
There is the Sunwayman M40A but thats kind of a awkward looking light.
I'm not really interested in 3/6/8 AA lights.
What else is there that's a good performer in 4AA format?
I'm interested in this too.

what about fenix ld40..
The only one I can think of offhand is this: http://www.thetorchsite.co.uk/LED_Lenser_P14_torch.html
Probably not what you're after, and I wish myself that there was more of a selection. I'd personally consider a 6 X AA, but I don't think I've ever come across one.
EDIT
Yes zeljco9r, I forgot the LD40. Good call. http://www.thetorchsite.co.uk/Fenix_LD40_LED_Torch.html
Good quality (but expensive) 6X AA battery light, Olight S65 - http://www.youtube.com/watch?v=xSUoDsm0_S0
I've owned the Sunwayman M40A for a few months now, and it's a beautiful light. I can post more info if interested. In any case, it typically goes for $120...I found it for $100 shipped at solarforcestore.com:

Just for the sake of conversation, why do ya'll want a 4 AA light?
Ability to fully (or nearly fully) drive an XM-L with increased runtime on safe batteries. 4AA lights can sometimes pull off alkaline use too.

Can't all AA lights could use alkies? Those Olights can anyway, very tempting. Very useful links, thanks. Never seen them before 
I think I prefer the form factor to soytnly's M40A (and the price). And there's a 3 X AA version as well..
@ kbark: What Garry said, really. The universal, hassle free availability of safe AA's is a very powerful argument for me.
Another vote for the Fenix LD40. It's a really nice 4AA light. I know you're not really interested in 3AA lights, but I have to mention that the Cyclone significantly outperforms the Fenix, nice light though the Fenix is: http://www.intl-outdoor.com/cyclone-c88-xml-u2-910lm-flashlight-p-349.html
Given the Cyclone's performance I'm not sure why you want to use more batteries for a light that has less throw & spill.
They weight about the same once the batteries are in. The Cyclone lacks the moonlight mode, however. Good luck deciding.
Ok I see. I'm just a fan of small single cell edc style lights.
Fenix LD40 is 4 x AA with an XP-G emitter
There is an LD41 coming soon that will be 4 x AA with an XM-L emitter
If you haven't tried a 2 x AA Caveman, I bet you would like that one a lot.
For 17 or 18 bucks you can also get the yellow Dorcy at sears or Walmart that is 4 x AA, and is s great thrower, but a rather narrow beam (XR-E emitter)
I'm looking for a light that my co-workers can get significant light output (as much as possible) on a medium setting for at least 4 hours usage. I don't think the Cyclone can do that (am I wrong?) on AA's. Also has to be compact to be carried in a holster on their side.

@ blinded
I've looked at that Cyclone a few times. It looks like it offers a lot for a very reasonable price, I just can't help feeling that a tail switch on a fatty is even more of a bad idea than usual..
Ok, I may have been wrong. According to _the_'s review, on Eneloops the Cyclone draws 0.53A on medium which I calculate 4.3hrs runtime on 2300mAh NiMh's. The Cyclone won't reach max output on NiMh cells (I'm estimating 600 lumens based on _the_'s mAh's) and the level it will put out won't last long. The 4AA's can reach max output and last longer. I estimate the Cyclone at 200 lumens at it's 0.53A tailcap current, while the Jetbeam PA40 is rated 468 lumens on Hi (yes less lumens) for 2.5hrs and 220 lumens for 6 hours.

@zeljko9r, its too close to the PA40 apart from a older emitter and a mode button instead of battery indicator. I bought the PA40 over that when I was considering them both.
@trooplewis, I bought the Dorcy CyberLight for my brother. It cost $27 with postage to Australia. Its pretty good for him but not for me.
The LD41 I don't really like, I am sure it will cost a fortune and it still has a lower ANSI lumen rating than the PA40 (also it looks ugly as hell) 
I will try to say something from my point of view. Why would anyone take the 4xAA instead of some today's most popular 1x18650 flashlight.
This would definetly be the main flashlight i would carry if i would go on long trip to unknown. Let's say hypothetically that you decided to pack your stuff on motorcycle and drive across Asia, through Mongolia, Siberia and so on, etc, etc. Possibility that you could find fancy batteries out there is equal to zero, and maybe less. But you must admit, there is possibility that some new panasonic protected batteris can die, catch fire and so on.. Why 4AA and not maybe 6AA or 3AA etc etc. In most cases AA can be bought only in pack of four, and also it's possible situation that some guy in Ulaanbaatar have only one last pack in the store :)
Because in an emergency where there is no power, you will not be able to recharge your 18650 batteries, but you can easily stockpile several hundred AA batteries that have a shelf life of 7 or 8 years.
Now if I could find a decent solar charger that would recharge my eneloops in a day, that might be an even more ideal solution.
All depends how much cash are you willing to spend. Don't know if they are any good but foldable solar panel seems nice. Check for Brunton foldable solar panel (cheaper solutions exist also, just try ebay). They come in various sizes and output currents. Combining that with some small quality stabilizer with 5 or 12v output would be serious stuff for carry around.
The problem with that is that you have to have a solar panel, a 12v battery, and an inverter to make it all work, not to mention some sort of voltage regulator. Rather stockpile AA’s from Costco.
