I've got an Infiniti. Have had it about 5 years and it cost me $700 at the time. The foot pedals are adjustable for height and stride length. It has various programs, but I usually just hop on and go. You can program it for different people too, male, female, etc and there are sensors on the non-moving handlebars that picks up your heart rate. It's also very stable and feels solid while not taking up much space. When trying them out when I was looking to buy, I found that the cheaper ones were very light and felt wobbly.
