Last night I found a CL posting for Pfaff Expression 2.0, never used for $500. After reading reviews and such, I was ready to pounce on that one and was soooooooo disappointed to find out it was already sold. But, it did get me to thinking about the wisdom, or lack thereof, of purchasing a previously owned machine, whether it was ever used or not. The warranty is only good for the original purchaser, right? I want to keep looking out for such a deal, but it is really a good idea? What is the likelihood of needing costly repairs? Just wondering ... just in case.
