With the approach of winter I am looking for an indoor trainer. I'm leaning toward a stand-alone unit like a Kettler ErgoRacer, LeMond Revmaster, Johnny G or the new CycleOps Indoor Cycle because (i) I don't really want to clamp my beloved road bike into a rear-wheel resistance trainer and bang away at it, and (ii) my wife might use a stationary bike to break up the monotony of her daily treadmill routine. Trouble is, these things aren't cheap and I have no real sense of their relative merits. The Kettler seems to use an "Electromagnetic Eddy Current Braking System" for resistance, which sounds like a more sophisticated approach than the felt/leather friction pads used on the others. And I assume (perhaps foolishly) that they all use standard road pedals. (I would fit clipless pedals and buy my wife a pair of shoes.)
Any advice would be much appreciated.
