I'd just like to throw another word out there about how incredibly freaking awesome OEM Laser Systems is. My PL-III peaked at 229mWs this afternoon, and it's rated at 100. Even with nearly dead batteries, it wouldn't drop below 145mWs. That is pretty insane... and, of course, absolutely perfect TEM00 at all times. I can't emphasize enough how great their products (or at least the ones they resell ) are. If you ever get the chance to get something from these guys, JUMP ON IT. you will not be disappointed.
