Edit; I should probably detete my post, I just realized I confused yours with model 6268, which is a completely different model, but for a while there it reminded me of a machine I once knew. The 6235 is a more basic model, still nice if it runs though.
It was a very fancy machine once, but they are 30 years old now, and computerised models tend to be a bit risky as the decades go by. They can be all fine though and still go on for yet a few decades, hard to know. They are not easy to repair when the circuit boards fail, if possible at all. If there comes a lot of monogram and emobroidery software with it, it should be worth something. They are the type of machine you can be found for anthing from $20 to $200, I don't know if they will go for much more. The top models with all the embroidery functions doesn't turn up that often.
