I had bought a Schwinn mag trainer at crappy tire here in Canada figuring that it was a good name in bikes. Paid $150 cdn, never really new when it was tight and after a while looked like the frame was bending. Tried to take it back for a refund, 7 day limit my flying patoot. Bought a Blackburn Trackstand Mag 3 trainer($175), only has 3 resistance levels but it locks up rock solid, basically becomes one with the bike.

As far as fluid trainers go I've heard that eventually they all leak, even Kurt Kinetics. Something to due with the fact that the silicone fluid that provides the resistance will find the tiniest gap and work its way out.
