I saw it myself at his house. It looks brand new....and works fine. I think I paid about 80 bucks for mine new, and I've had it for over 3 years now. Its kinda bulky......the 4" dryer hose fits over the round side which is actually the inlet. They move a ton of air!
That's the best I can tell you. It's not some ragged out piece of crap on it's death bed. I'd trade some frags, or drop 40 bucks no sweat if I didn't already have one. It's not really something for a small system though. I have mine so that it sucks the hot air out my canopy and blows it toward my ceiling fan......Not only does it help cool off the tank, but it keeps the tank area from becoming a hot spot. Before I cranked it up, it got pretty warm on that side with the halides and chiller running
