You can't really do cheaper than a Slimserver -- it's free! The Squeezebox hardware is what costs money, and it's worth the money from what I've heard.
I have a P2-233 running Winamp, listening to an mp3 stream from Slimserver running on another PC. It's setup in my family room, with a wireless card and no peripherals. It works flawlessly.
Slimserver can stream to many different computers, different music or the same music, but I don't know how in sync it would be. I haven't been using it long, but I'm very impressed. The only downside is the ~5 second delay for buffering -- when you switch songs on the fly, there is a 5 second delay. This may be configurable. The fact that it's open source, free, and can use plug-in's makes it pretty unbeatable, IMHO.
