I will.
So far, the C88 E1320 modded for me is real nice. Great thrower. High quality light. Current plans for this C88 light are to test these batteries: http://www.amazon.com/Sanyo-Capacity-Pre-Charged-Rechargeable-Batteries/dp/B0058GZWXQ/ref=pd_cp__2

I believe my C88 falls outside your parameters in several areas. I like it a lot, and I'm glad I have it, but I don't believe this is the "ultimate patrol light." I do like the versatility of its AA battery usage.
My TF-R2 resides on my duty belt as my current compact patrol/search light. No downsides to this light. But it falls outside your parameters in terms of size. I don't mind it's size, and I like the form factor better than the C88, but your criteria seems to call for a P60-size light.
Current plans for the TF-R2 are to put in a Cutter U2 1C emitter driven at 4.2A, in either H-M-L or H-M-strobe. This light is awesome, takes P60 pills, and it throws. My modding plans also push this light past your criteria in terms of price. I paid $20 for the light with a Q5 LED, but I put in a generic T6 I had laying around, and a custom U2 drop-in will cost about $50.
I ordered http://www.tmart.com/BeamTech-BT4000-CREE-XMT6-18W-2700LM-5-Mode-Flashlight-Gray_p136640.html on 12-11-11, I think the day it was listed. Now I got a message this is backordered. I'm very hopeful about this configuration. Do you own a 3xT6 light? If not, you have to use one on patrol at night to appreciate it. While my SR3800 is uncomfortable on the duty belt, it does sit by my side in a cup holder in the patrol vehicle...
I ordered http://www.dealextreme.com/p/fandyfire-hd2010-cree-xm-l-t6-600lm-5-mode-white-led-flashlight-1-x-18650-107154 and like the TF-R2 this is getting a U2 LED emitter.
However, I'm most curious about getting the BT4000 into my hands for testing. But its $50, $30 over your price criteria. But a 3xT6 and 1x26650 at $50 is well worth it, if you users would be willing to carry it...
I still have yet to order one of these: http://www.lightmalls.com/rq-07-cree-xml-u2-5-mode-led-flashlight-1-18650 I can't help but think your users would find this useful. I use (carry daily) this host with a T6 created by E1320 (Erik). It is a T6 1A (but tint looks like a 1C) driven at 3.1A and H-M-L. Damn near perfect patrol light. Compact, and with Erik's drop-in it actually throws okay. I have a U2 3.1A drop-in I've tested in this host, but Erik's T6 is better. Nonetheless, I'm curious about that U2 version for $20 I linked above...
