I saw them at the local DJ store, I wasn't all to impressed. They weren't very bright at all, and their action was less than 'acceptable' for me. They were very choppy in movement and jumped around the room instead of 'scanning' They seem to lack any fine control because of their 1.8 (Degree symbol inserted here) stepper motors.
For the price, I guess they are alright, I was also comparing some moving heads that day so maybe my expectations were a bit high.
