Here's the thing there are no
GOOD CMY fixtures for under $1500. There are cheap knock offs in that price range but they are likely to barely outlast their warranty, if they have a warranty at all. They are from Chinese import companies who make them cheap and then may disappear so if you ever have a problem a year from now you will be stuck with an expensive doorstop that is impossible to repair. Don't buy them.
So Let's try it this way. What follows is a list of reputable dealers. Some are high quality (and you may not even be able to afford them used), others are lower quality but at least they are going to be in business next month if you have a problem. I would not buy any moving light
fixture unless it's from one of these companies:
Martin, High End,
Elation, Chauvet, American DJ, Robe, Clay Packy,
Coemar, and
Vari-lite. (... did I miss anything?)
Probably the cheapest option is to put a
Seachanger XG
Wash on a
Source Four, make it move with either a
Rosco I-cue or
Apollo Right Arm. For around $2500-$3000 each depending on if you need
power supplies,
DMX cable and the quantity you are purchasing. That's probably about the cheapest
CMY wash option out there. From there, you probably are looking at something from
Elation in the closer to $4k range. Or go used. You can find some good deals used.
