Go to Amazon and look at the Nitecore MT2A or MT1C. Nitecore seems to have some of the best-valued lights around; I'm hanging out in the hospital with my wife (c-section 2 days ago) and I've been reading reviews on forums and such for a long time today. Also, for $55 or $60 you can get a 4Sevens flashlight. People seem to rave about them. Foursevens.com. Check out the Quark Pro, Quark Tactical, and mini lines there.
