I do know I can buy a G1 for 25,
But I have noticed a few people selling 9mm builds without the stock lens,
So Im hopeing to pick them up for less than 25
I have one that I will not use. It has some kind of artifact right at the center of the lens so the spot has a lot of splash. You can have it for $5 if you want to mess with it. Probably not good for anything other than a medium powered 405nm build.
