People seem to like the portable aspect of these machines, if they are class-goers. I collected a couple of these but honestly never use them. If I had a big room I might have them out on display, as it is a novelty. Or wouldn't they be cute pointed towards each other, as bookends with a few quilting books in between them?
I have since collected a couple of 301's, and like those machines a lot more than the featherweight. They are gear driven and sew stronger than a little belt driven machine (as the FW). They also slant towards the user (the first Slant-O-Matics) which makes everything so much easier to see.
If you have no use for it and don't want it, sell it! One in that good shape (cosmetically) would probably go for $400-450. And that's nothing to sneeze at!
