I have the Pacemaster Gold Fold. It is a great treadmill. I tried many, read tons, and chose this one. Oddly enough, the folding seems to be more stable than the nonfolding in this brand. I had read that but wasn't sure about it, but they delivered the wrong one to me so I had the nonfolding one for a while. Sure enough, the folding one is more stable. The guy at the store said it had to do with the frame, I think. I have also had a couple of questions about it that the store wasn't able to help with and I emailed them and heard right back via email and a phone call. If you go with the Pacemaster, be sure to get the VR one (Virtual Reality). That just gives you a few courses that are programmed in - really not that big of a deal, but you will know you have the most recent model. Lots of stores have both still.
