I called about my 330 and was told by Viking it had a book value of $250. I probably wouldn't get that for it and your is older. They will tell you if you call them and that should give you some idea. Those are workhorse machines and well worth the money for a first time sewer. Because it's mechanical and not computerized the market is more limited to those wanting those kinds of machine. I kept mine for a back up to my back up machine. I would say somewhere in the $175 - $200 range.
