I just purchased a new one on ebay for $220 + $20 shipping and I thought that was a good deal. Your price, if it is new, is killer.

I like the Fluid2. My old trainer is a mag. Blackburn and I've found the Fluid2 to be MUCH quiter and a lot smoother. Should produce a better winter's worth of training.

Computrainer uses a proprietary trainer. I emailed them your identical question about 3 weeks ago and here is their reply:\

"The Computrainer Comes with it's own trainer, you mount your bike onto the stand with the rear tire against the load generator, attach the spinscan magnets, all these components plug into the handlebar controller, the handlebar controller is capable of operating the unit but it is strongly recommended that you then hook that into a computer running our software. The software is not compatible with other trainers."
