We would save some money and buy the X6000.
The X6200 is a very good elliptical, but with the X6000 at $1199 it makes it hard to recommend. I would go with the X6000 over the X6200. If you like folding ellipticals, which I don't, then by all means buy the X6200. For $400 extra I would have a hard time paying the extra money.
