From West Allis, Wisconsin, "Welcome Gary"; Do you know what year the machine is? If all you stated is accurate, then the $339 USD is a STEAL. Even if you have to put (UP TO) $1,000.00 USD into it you will still be ahead. (Provided that the machine isn't TOO old) And any mechanical parts you may need should still be pretty easy to get and available through Argo. But body parts (engine cover/floor etc) might get tricky. Again this all teeters on how old the machine is. If it is less than 5 or 6 years old, I think you are pretty safe in obtaining parts. Plus, there are ALOT of members here that would probably have what you parts you may have a hard time locating. Or they can direct you to where to get them.
It's all just nuts and bolts.
