That would be the worst waste of money you did in a lifetime. :)
You should put in the dimensions to get a feel for thier size.
My vote is for #3. But I like small powerfull lights.Others might prefer the bigger sizes.
Nice job!!!
the dimensions will be longer by 1 - 5cm than normal flashlight you can find/owned because of the heatsink being thicker
Budgeteer - haha you are right, i have edited my post 
no one like flashlight 4? 
(except for one guy)
Frankly i have a very delicate taste for flashights. Not a single one makes me drool. Not bad fuctionally wise designs and great heatsinking capabilities tough.
I like these designs:
Even this crazy Alien style cheesy flashlight
Sorry for the long post. These are only a few designs i do really like.
I like that clip on the Gizmo, looks Similar to what i just got in the mail today by a larger scale company
Definitely some interesting designs, Id love to see what another round of antialised images can bring ;)
#1 with the tailcap fluted like #2!
#2 has my vote. Gotta love the stubbies!
#2 with only 1 XM-L, would probably be good "compact" thrower with great runtime.
