Ok, here's my dilemma, I've ventured into a hobby that is not exactly centered around students with school loans to be paid back but I can't help it. I must build a projector!! 445's are no problem as they are quite cheap, but green on the other hand has me thinking hard about what I should do. I will be using 1W of blue so I figured about 300mW of green should be sufficient. The problem is that I really can't afford $400 for one laser. So unless I can find somebody with an old one lying around that they are willing to let go for no more than $200 the only other solution I can think of is using 2 of the cheap 150mW modules you can get off eBay. I guess my question is would two of those modules perform well enough for a first projector, or am I risking more hastle than would be worth saving the $200? I would plan on replacing the drivers that come with the modules to something better that can handle analog modulation. Any advice? I will also have the same issue when it comes to red, except I know I will need just about as much red as I have blue Anyway, any thoughts, advice, or links to cheap/used 532/640 lasers would be greatly appreciated. I will be keeping a close eye on the buy/sell forum here also Thanks!! -Luke
