normaly you will get about 130-170 if your lucky, with dx lasers that high it kinda vareies, some work great and live for many years, others will break pracitly right when you get them... its all a gamble but for the price its hard to complain.
Techlasers are the same people as WL, and all their products are cheap chinese duplicates.
You want cheap, DealExtreme. You want quality, Nova, Optotronics, etc.
