FWIW, I was at Sears yesterday and hopped up on the Sole F85. Nice machine. Quieter than even the other Sole we tried (F80). Comfortable to run on.
I really like the lifetime warranty, the 22" wide running deck (vs. 20" for a lot of others - those extra 2" are welcome), the 3.5 cph motor that is surprisingly low profile, and the ability to easily fold. I hadn't given that last feature a thought, but DH pointed out that it would be handy in the area where we want to keep it, so we can still maintain access to the utility room beyond it.
I might have sprung for it, but we still want to try the guys at Heartline.
Also went to D_i-c-k's and were not impressed with the Livestrong. Seemed gimmicky and the knobs/joystick thingy looked cheap.
