I have a spacelas 500mW RGV projector.. It came with the red diode driver board broken (a loose connection). But they were real helpful and responsive to emails. They offered to fix it for free, or send a new red module, but I managed to fix it by myself. Also the projector was kind of underpowered. It was advertised as 200/100/200 RGB, but it was really about 150/100/140.
