I haven't had much luck with this.

Most of the major chains don't carry something this big, and trying to google for it online keeps getting me results for the wrong kind of switch, like 8x8 matrix switches, switches as in networking, or $1000+ studio equiptment.

I am looking for a device that can take 8 composite inputs (with audio) and has one composite output, and lets me switch between which one I want.

The closest I found was this device on FRY'S, which is only 6 ports (great price though):

Anybody know where I can get something like that but 8 ports?
