Prices vary. I have 4 FWs... $280 at an auction, $250 including a FW cabinet at an estate sale, $225 on CL, and $80 at an estate sale. All are in great shape and some have extra attachments...some have no attachments. Just keep your eyes open. There are lots of them still out there. As you can see, I have trouble passing them up.
I don't know about 301 prices but I would think much less than FWs. I would expect less than $50 around here.
