I would say in rank order - condition; accessories; geography; scroll vs straight face plate. But in reality, geography is going to be the great dictator. A friend found mine for me. He only wanted $25. I paid him a bit more. People in this general area ask anywhere from $200-$600 on Craigslist in decent/good condition. Yet another board member here got one at a garage sale recently for $25. A little rough, no case/accessories. I'm cheap. I'll wait/look for a long time before spending big bucks on something like that. Last year picked up an electrified red eye for $50. Needs a bit of refurb but in (I think) overall decent condition.

I got mine for $240/ cash. I was told $500-750.
It depends on whos buying and how badly they want it. Mine came clean, with accessories and a case.

There's only white and black, but the white has a faint greenish tinge (some people claim it's turquoise) so people get confused and think it's a third color. The white ones generally sell for more, because there are not as many of them, but the black ones are supposed to be slightly better at sewing. I think price depends mostly on whether the seller knows what the item is (ridiculously low prices from those who do not know, and very happy buyers) and on whether, knowing what it is, he jumps to the conclusion that it's made of gold (ridiculously high prices from those sellers, but usually no buyers).

There is also a tan one. I am looking for a tan one now.

Love those featherweights, they were also made in Tan, made in Canada, same style as the White ones, plain Jane, no decals but "cute" also, they were in a brown and cream colored case. Ruth

Look at the small details of condition, wait it out. There are machines up for bid everyday...so don't rush and you will find the one! Good luck.

I got mine for $75.00 guy was asking $250 but he needed cash and I pointed out the flaws...they weren't bad but he thought the value was greatly lessened by them....he got his cash, I got a great little featherweight

Marketing 101: it is a fair price if you are willing to pay it. This is one of the basic rules of marketing.

I got both of mine for around $100. Both were in great shape. One has accessories and one doesn't. I figured for that price, I could buy some accessories for her! They are advertised around here for $350-$500.

My SMG buys them from estate and garage sales, refurbishes and sells them on ebay. I got a free one from someone and he checked it out for me. He told me not to buy a white one because they weren't made as good as the black ones (by the time they came out with the white ones, I guess Singer was cost-cutting). His advice to me if I wanted to find another: go to estate sales and rummage around in the back of the closets, basements or garages. That's where he finds FWs that nobody thinks are anything but an old sewing machine and he gets good prices then.
