Mine is a cheapo I bought for 9K two years ago. Still OK. Non descript brand, called in for service once -needed some oil. Will probably need new "band" soon. It is foldable, taked very little space, but weights a ton. It is also the most basic model, no bells and whisltles It is getting less use now that I've got the elliptical. It is very noisy, too.
Where I got my elliptical, Takashima store in Danshui, they also had pretty nice treadmills. If I didn't have mine, I'd take theirs. Here some:
