Buying a Tunturi elliptical for $3600 is sheer madness
In the $2000 price range I am willing to give Tunturi the benefit of the doubt, but at $3600 I am not willing to cut anyone any slack. For this kind of money you have to be buying quality, features, and name recognition. Unfortunately Tunturi falls far, far short. Consider some of their lesser priced units if you like their feel but otherwise try some better known premium brands.
