I know someone who bought an ElliptiGo. It is similar to your product above. I wasn't impressed with the quality of construction but I like the concept. The gear system made a very noticeable sound when in-stride for some reason....I had assumed it was a cheap $299 mail order deal, but when I checked online, was surprised at the entry level model starts around $1800. This sort of exercise is supposedly a lot less harmful to your back and neck than traditional biking. If you are adverse to traditional biking due to injury or age, I'd suggest a recumbent trike...Greenspeed makes some great equipment that you can link in tandem or go solo.
