Copy/paste from my reply to another thread a few days ago:
I just received a 1up last week. I'm using it to recover from a serious ankle injury so I've only done some very short/light "workouts" but it seems quiet and very well-built. It's my first trainer so I don't have anything to compare it to.
I was going to get a Kurt Kinetic because it gets great reviews as well, but after talking with the friendly owner at 1up I went with it because of the exceptional warranty (lifetime), 60-day money back (plus they pay for return shipping), their reputation for excellent customer service, and the fact it's made in the US (most others are made in China, of course).
