I tried out a Bowflex treadclimber because I was convinced I wanted one. I didn't care for it at all. It isn't as versitile as a plain treadmill. I'd rather have one with a great incline when I want a tushie workout but just a great wide belt when I want to walk or jog flat. I haven't tried either of the treadmills you listed, but I've heard good things about Sole. I have a Trimline treadmill that I love, but that and the treadclimber were all I tried.
Have you looked at the treadmill doctor? I'm not sure of the exact site name, but google treadmill doctor. Awesome advice. Definately narrowed down my search. Good luck!
