I think that we have talked on your thread about the hnk S06J LASER diode, but I don't remember to have insulted sbd.
I'm investigating what are these diodes. Also, I need NFO on the Chinese lens sold on ebay - which one is good, which is better, whid doesn't worth the $15 they want. That's it.
We also are trying to create a cheap LPM in a thread here.
