Need something to accecpt many audio inputs for cheap

Hey, I need something that I can plug a few (at least 3) different audio sources (all a/v type connectors). I want to be able to put put these to a cheaper set of computer or home audio speakers (preferably regular cpu speakers). Also if it had other inputs (assorted jacks) would be very helpful. Im trying to keep this low budget. Can anyone explain to me what I should be searching ebay for?
