Choosing a bike trainer

Hey guys,
Am going to buy a trainer so that I can ride indoors when the weather outdoors is too nasty.
Have read about the Kurt Kinetic trainer, and it seems to be a good design and well built. I particularly like the fact that the fluid cannot leak out because of the use of magnetic coupling in the drive unit. Am leaning toward the Pr unit which allows the option of adding a 12 lb. flywheel to the 6 lb. standard flywheel. We don't have any mountains nearby, but at least I can get a good simulation of the workload.
Kinetic also makes a Rock-n-Roll frame that simulates the oscillating motion of a bike on the road. Would the rocking be a problem for our FWD bikes, or would it work out fine?
Any advice before I pull the trigger?
Thanks,
Daniel
