I don't think it's bad but I just want to make sure. I bought it from a shop where the guy used it as his regular machine, and they also repair machines there, so it was kept up as far as maintenance. Thanks for the links-I will check that out. I emailed the man who wrote the book I mentioned but haven't heard back yet. It's an hour to the shop so I would rather just check it because like I mentioned, I think it's probably fine.
