My sister read your post here and called to be sure I read this and answered! She is in Mesa, AZ LOL
I'm not a FW 'expert' although I sewed on one when I was a kid and I have refurbished a few - If you can get one that has been serviced for that price with a warranty from someone reputable I'd say go for it. Especially if you don't have to ship it - right there you saved $50 - $75 I think. If you figure how much those cost 60 years ago then allow for inflation, it is still a good deal - a new sewing machine will not hold up as long so will cost you a lot more money. It looks to me like the advice above is good. I hope you find one you really love. At the same time don't rule out a nice Singer 301
