I have plenty of LED's and they're fine for most uses.... but for real work, I still use a Surefire. Brinkmann maxfire delivers an almost identical beam (focus free, no rings, same brightness and beam diameter) for $19.99 with batteries, and while it's not as well constructed (plastic instead of aluminum) I haven't broken one yet!

CR123 can be expensive depending on where you look, but if you order from Surefire or have a local distributer near you, you can get 12 for $15 which isn't too shabby at all <img src="/images/graemlins/smile.gif" alt="" />
