All Channel Stereo Receiver

I'm looking for a receiver for my garage that will power 6 speakers and will only be used for playing music (iPod/radio). It seems I would need a 7.1 receiver with the 'all channel stereo' function.

Can anyone recommend a low priced ($200) receiver with ~100W per channel? This is just for the garage, so I'm looking for something priced well and am also open to used units, so if there are old models that will bit the bill, please let me know.

Thanks in advance!

Thanks, I too am in the Bay Area. I've been looking on craigslist but haven't been able to determine if the receivers have all-channel stereo function. Here are a few that i found on craigslist, and based on the owners manuals, they don't seem to have the all-channel stereo function. Is this a feature that is rare in receivers? Or are there certain manufactures that don't offer that feature and others that do?
