I am thinking of buying a Norditrac like ski exercise machine, like CSA Alpine
Ski machine, or something like that. I remember seeing someone mentioning that Norditrac is the best exerciser in the market. But since Norditrac is kinda pricy to me, I am thinking alternatives. These others have the similar design, that exercises both lower and upper body at the same time, I 'd like to hear from people who have used such machines.
