Well I found one at a thrift store and only paid $9.95 for it and it was in good condition...wiring and all. Just needed the base adjusted and a needle, which I took care of. The serial number is underneath so you would have to take out the bolt in the bottom and look for it under side of the machine. Look on Ebay at what they go for......more than what they are asking for the one you're looking at. It all depends on priorities, hon.
