I picked up a WD 1000BB from a local large retailer (Sam's Club) for US$125 ($225 - $100 MIR). I'm pretty pleased with it. It's pretty fast, pretty quiet, mostly cool and has been running great for me during the last month. The seek times are pretty awful, but the transfer rates are very high.
It wasn't difficult at all to set up, and there's no compression on it. It's a true 100GB drive (using the goofy MB definition of the HD manufacturers, anyway).
