I assumed you could easily purchase one of these since there is a link to a kit already earlier in the thread. It's the one I thought we were talking about all along. The one you have to add the 110 volt outlets. In an attempt to clarify for you I have reread the thread and done some googling. What I found is that my memory of these during the 1970's was spot on. Unfortunately, while they were easily commercially available (Radio Shack e.g.) back then, their popularity has waned in the post disco era. Disco never died for me, but that's another, more troubling story.
So what happened? Very few individuals ever bought these devices. They were sold to dance clubs. I'm guessing the dance clubs now are featuring large plasma displays or front projection technology and lasers because no commercial preassembled color organs jumped immediately to my attention on google, but there were MILLIONS of hits. MANY MANY MANY kits and naked circuit designs exist for both incandescent and led light color organs. If you are enough of an electronics hobbyist you will have no problems. You will likely need soldering skills, perhaps some ability to read electrical schematics (probably kit dependent). You might even get lucky on Ebay and find one of the myriad 1970's units. The one I actually owned back then was a kit put together by a friend of mine he sold me when he got tired of it. The kits I've seen on the web seem to be for less than fifty bucks. Most do not appear to include the case or the A/C outlets (which makes some sense since it appears some of these units are capable of 110 or 220v).
The best light show available to most of us would be a DLP front projector running a winamp visualization (or similar). If you own a PC then it's just the cost of the DLP, which can also double/triple as a game display, TV etc. DLP's and similar projectors are now available from about $600 and up. The fifty dollar color organ kits of 1970 are still about fifty dollars. Figure you'd probably be out close to $100 by the time you got all the pieces together for the color organ (depends a lot on what kind of lights you intend to hook up - my raw Christmas tree bulbs strings were cheap enough, but I still had to build a 'display window' to use them. I mounted them flush into the wall and covered them with a 2' x 4' plastic panel like the ones used to diffuse fluorescent lighting).
