Since there are no other reviews for this treadmill yet, I thought I should throw in my two cents to help anyone who may be thinking of purchasing. I've owned the ProGear 350 for a few days and am so far very happy with it. I'm a slender woman with mild arthritis and was able to assemble it on my own with little difficulty. The written instructions are sort of convoluted, so for me it was easier to toss them aside and just look at the pieces and figure it out -- very straightforward. The treadmill works great and the motor is quiet. I bought this particular model after looking at many options for these reasons: 1) The price (I paid under $300 on Black Friday and this included the 3-year protection plan); 2) The size of the belt (about the longest/widest I could find for the price point -- you can take long strides without falling off); 3) The footprint when folded up (easy to fold and is compact, so takes up little space in my apartment and can be rolled away into a closet). Like I said, I'm thrilled with it so far, but of course if anything should go wrong I'm glad I have the protection plan to back me up!
