I have good experience with anything CycleOps. Saris owns them now and its based just a few minutes away from where I live. I don't know anyone who owns any other trainers or rollers than CycleOps, and the only bad thing I've heard about them ever is that the cheaper trainers definitely sound like a small airplane taking off if you're really going at it. The rollers are great in my experience, but most of my experience is what other people tell me. I'm just too tall to do rollers, my center of gravity is too high for me to get on them (...thats my story and I'm sticking to it).
