There is not such a thing as RGB laser. They are all made of 3 lasers R G and B. Also there is no such a thing as quality and cheap. You choose one. Cheap is cheap and quality is quality. To make it clear, post how much money you want to spend and we will give you idea where to find one for your budget. But be sure that you put a side at least $5.000+ Also it would be good to know what is the purpose for this RGB you're looking for.
I hired an Italian guy to do my wires. Now they look like spaghetti!
