Suggestions for an AR-15 light?

[Dafapa]

I'm trying to find a weapon light to mount to a quad rail hand guard on my AR-15. Can anyone recommend one that is bright enough, durable, and won't break the bank? I'd like to find one with push button operation (not a fan of the remote switch ones) that takes AAs, but it looks like I may have to settle for using CR123 batteries. I've seen some promising options around 50-60 dollars, but I'm uncertain of using them on a weapon. I'm hoping to avoid 100+ dollars for a weapon light.

Looks good. What do you have it mounted on?

Watch e-bay real close... I snagged a Surefire M951 off there for a bill and a half. Kinda hard to beat that.
