What is the value of a pfaff tipmatic 6122?

I paid $350 for mine on Craigslist and I see that someone put a Pfaff Select 3.0 (which is functionally the same machine) on Craigslist for $375 so I would say somewhere between $300 and $400.

You could make the argument that the Pfaff Tipmatic 6122 is better than the Pfaff Select 3.0 (even though the 3.0 is the newer machine) because the Pfaff Tipmatic 6122 was one of the last Pfaffs made in Germany. The Select 3.0 (and all newer Pfaffs) are made in China. That's why they say "German Engineering" instead of "Made In Germany" on them.
