I will admit, however, that most of the people that built their own projectors have done so because they want to be able to do everything. Complex beam shows, vivid graphics, cool animations, and full-color. But if someone isn't interested in all that, your point is valid - there are some off-the-shelf solutions that can do basic beams very well. It's just that my experience has always shown that once a person gets a taste of what a laser projector can do, they want *more*. So if you even think that you're going to head down that upgrade path, it makes good financial sense to purchase a decent controller right up front. From Buffo
