I went back and forth on whether to buy used or new, and opted for the more convenient option. In hindsight, I wish I would have found something better. I had to do some re-drilling of a hole to get the front post to align better, and even still it's not square. The handles are pretty close together, which makes it difficult for even average sized people to not bump into them. Also, something with a foot plate will work better than just these rollers that keep the heel in place. In the end, I can still do back extensions, and the folding ability gives it a small footprint, so it could be worse.
