Thanks for the replies
My budget is somewhat flexible at this point. I was originally thinking $100 or less for speakers and now that I need an amplifier or something, I was thinking $50-100 for that.
Just looking around at popular electronics sites (circuit city, best buy, etc), it appears that cheap receivers are cheaper than cheap amps. Seeing as receivers have bells and whistles on them, it would make sense that amps have better sound quality, right? If so, how much better?
Also, earlier today, I saw a pair of Polk S4 shelf speakers for $30 on an I-gotta-sell-my-stuff poster on a bulletin board. It sounds like a pretty sweet deal to me. Anyone know anything about these? (Info online is pretty scarce; all I could find is that they are two-way with a 6 1/4" woofer.) Should I bite?
