For a real cheapie, I can also recommend the Antique Electronics Supply K-502 kit, an integrated stereo amp for $139.50. I put one together in a couple of hours "bone stock", as they say, and it sounds great with a pair of diy speakers in my garage/shop. The only thing I'd change if I were using it as my principal amp would be to upgrade the pot.

One of the nice things about kits and parts companies is how amazingly responsive and high quality the offerings and people are. In my years doing this, I've only had one less-than-satisfactory experience, and that company is no longer with us.
