How good REALLY is the Peachtree Grand Integrated?

"Giant killer" is an oft-used term in this hobby of ours. I want to know if what I've heard is true; that Peachtree could not get dealers to stock this piece because they found that this $4500 piece routinely killed their sales of $20,000 systems.

I am considering buying a refurbished unit for $3000 and would like opinions on whether this stacks up to pieces like the Krell Integrated or the NAIT units. Basically, what else should I consider at this price point? Or am I not going to do better unless I spend significantly more dough? Thanks!
