hi guys, I've heard that the airdyne is one of the better pieces of cardio equipment next to the Concept 2 and versa climber. A friend of a friend of a friend is selling one for ~ $150 bucks (supposedly very good condition).
I haven't used one before and was wondering if this is a good deal (new they are around $550, so it appears so) ? I'm gonna take a look at it soon, and I was wondering what to specifically check out. Anything else I should know/ consider?
