Just thought I would chime in...
I know people who have both Life Fitness and Precor ellipticals and love them. I have the Arc Trainer. I would not recommend the 350 or 360A. I had both and nothing but problems. Maybe they have worked solutions to them though - can't say - so don't go by just what I have to say. Now I have the 425 and it needs new bearings but they are fixing that. It is a GREAT workout. I feel it on that machine completely differently than on my stepmill, treadmill or bike. And, I have never experienced such wonderful customer service as I have from Cybex. I prefer the arc to ellipticals b/c it doesn't hurt my knees or back like ellipticals eventually do.
