I have a dead Lasever 50mw 473nm module. I sold the driver separately so I don't have that. This module put out 100mw when I first got it and it was barely used. It sat on the shelf most of the time and died from just sitting there. More than likely, the seals leaked and the crystal became contaminated. Maybe you can salvage parts of it. Some parts in it that might be worth salvaging are the enclosure / lens mount, TEC, IR diode, etc. Asking $40 since that feels about right. I can ship in USA for $5. Probably not worth it to ship outside of USA.
