Steve, for the price, it's kind of hard to beat. However, I'd bet that his rating is WAY overstated...
I know Mike had some problems with his Tradewinds chiller - but mine has been outstanding, as have several others. It uses a Copeland compressor. Google them and call and talk to Hal. He does occasionally have one that he can sell direct (a scratch and dent). I got a 2/3 hp unit for around $600. It's a beast.
