I will be selling some 400mw 532nm laser diodes in the coming week. You can check eBay for some great prices for individual purchases. I will also work out a group buy if enough people are interested. I already have the least expensive high quality laser units on eBay. Checkout username: magicmerlin8vi5 . Also, check out all the positive feedbacks and comments about the lasers. You will be pleasantly surprised. Buy from me if you want to save hundreds! I also have special deals on combo pricing of Full Auto Laser Animation software, Cambridge style galvos and from 300-500mw 532nm lasers.
