If you are only looking for DJ gear. Give up on
CMY and head straight for the American DJ and Chauvet websites. You'll find things that change colors and do tricks in your price range. But be warned these fixtures are intended for use in a dark night club. If you try to use them on a fully lit
stage you won't be able to see them.
If you want professional grade brightness and a
CMY moving head
fixture that has a
stage quality output they are going to cost you at least $5000 new. You can get used ones for half that. There simply is no such thing as a professional
stage quality
CMY fixture for $500... even used. You might be able to find some decent quality used moving head fixtures that have color changing wheels for around $1000 but not with
CMY. Used professional quality
CMY fixtures in working condition are probably going to run over $2000 each. Also remember that you are going to pay hundreds of dollars to replace a single lamp in fixtures of this
level. So your ongoing maintenance is high.
You might want to check out the products from Neo-Neon. They are a Chinese
OEM manufacturer for several of the lower end main stream products. You can get an Elation/Chauvet entry
level quality
CMY moving light fixtures for a lot less money. Supposedly, it's the same parts and same quality.
