If you're comfortable with a soldering iron, you can build a Hagerman Bugle for about $60:

The half-kit includes a very nice circuit board and easy instructions. I got Texas Instruments to sample me a couple different kinds of op-amps so I could experiment. It sounds great and since it's battery operated, dead silent even at 60dB. I've heard the NAD PP-2 and liked the Bugle better, especially since I can adjust the gain in small increments.
