I have 3 featherweights - I paid $325.00 for my first one and the other 2 were around $200.00. But the lowest priced one I had to replace the foot pedal & cord (that is one piece) because the original owner had lost it, but everything else was there.
It all depends on what you want to do with it. They are very reliable, very portable and cute. You won't find a lighter vintage machine. The stitches are limited. Some do not do a reverse stitch, not sure when they introduced it.
For some odd reason they are very addictive. Don't know why, maybe it is like the beanie baby craze, or maybe because they have some hypnotic sound when you sew on them. Not sure what it is, but it does appear you can't own just one.
