Player8,
Did you read the thread? There are many folks buying these things off Ebay for under $300. They also mention Ebay power sellers that you can by direct from. The thread goes on and on, but worth reading.

I have absolutely no personal experience with pro-amps, but from reading that thread, I'm very interested. They seem to good to be true. At audioholics, the question was asked "why don't people use pro-amps for home use" and the predominant answer was that audio snobs just don't like them. They aren't pretty enough. But from sound quality and power, they do every bit as good as main line home systems.

One noticeable con is that they have fans and the fans can be heard at low volumes. Not that big a deal to me.
