I like my TLR-1's. I currently have two and have had no problems with either one. I had a Surefire X300 that quit working on me and I have it rigged now so it still works but not really my first choice anymore. I've looked at the TLR-2 but can't really justify the extra cost just for the laser.
I have a TLR-1s that I picked up for around $110 and im very happy with it. Mounted great, functions are easily within reach and seem build very well. The only issue I would have with it is engaging the strobe function for constant on. It takes quick fingers and a smooth action. But other than that a great product!
