I just bought the Outpost.com Polk R30's for $40 each and that's my impetus to upgrade my setup. Right now I have some cheapo RCA receiver that I'd very much like to upgrade. I already have a pretty decent subwoofer, so I need a center channel and a good receiver. I can get the CSi25 on eBay for about $100 new, so something $80 or less would be ideal. I'll consider almost anything as a DD receiver. Also looking for sub-$100. Thanks!
