Yeah, 'system selectors' or AV switchboxes. Radio Shack sells a 4-port one fo $19.99 - I have two of those daisy chained to my television, which is enough to support all the RCA/S-Video consoles that I use. For RF stuff, you can daisy chain those as well. If you use component video, RGB, or optical/coax audio with any of your consoles, you may need something more elaborate, but it doesn't sound like that's the case. I currently have a GC, DC, Saturn, 2 Genesis units, an SNES, a Neo Geo, an Atari VCS, a VCR, a PC, and a DVD player hooked up, and the most I ever have to do is press two buttons on the switches and maybe a button on the remote for the TV or receiver.
