I’m going to quote someone that has done more research into specific lasers.

If you asked me today to buy a ready-to-burn laser, I’d go for the one from Barnett Unlimited on eBay. Nice design, known diode, big fan, diode protection, and seems to be well respected over at laserpointerforums.com 3 (Shmackitup)

If you click that it will take you to the thread where he does a breakdown on alot of the major laser options.
