We've bought a lot of stationary LED fixtures from China and some clones of a couple popular movers.
Every factory is different regarding QC, parts, and consistency from run to run. After 3 years of dealing with the inconsistency and zero technical support (why won't this fixture run with a generic RBG profile?, oh, every DMX channel is *backwards* counted) we won't buy direct from China anymore.
What I would do: buy a pair of whatever you're interested in and try them out. If you don't like them put them on Craig's list and some DJ will buy them just to run in demo mode.
Nothing about moving lights is compatible with inexperienced operators if it requires more than pushing a "go" button. Seriously.
