I have the Kurt Kinetic Road Machine (the fluid trainer) and really like it. I tested it against the Cycleops Fluid 2 trainer and while they both felt solid I preferred the way the Kurt Kinetic felt. It seemed to feel more stable somehow, and just more solid. I am sure there are others who would say the reverse, that was just my personal opinion after the test.

Do you have the option of taking your bike to the LBS and trying them both out with the bike you will be using? That really helped me to make up my mind.
