I hunted for a FW for years - they are very hard to find in AZ - as most people won't part with them. They sew wonderfully and I too love the 'sound' they make, it's soothing.
I found mine at an Estate Sale - I got to the sale at 5AM in order to be sure I was the first in the door - they hand out numbers at 6 AM and the sale started at 7AM. I walked in and said "that's mine!". I got a great deal $150.00, most of the FW's here in town go for $350 and up. My FW appears to have been in AZ most of it's life as the case is perfect, no moldy smells and the key was with it. I understand a lot of the cases are missing the key, so this was an added plus for me.
I use it for piecing and the stitch is perfect and super easy to care for. Mine is from 1938 (72 she is!) and still going strong.
DH has strict instructions to pass along to my granddaughter. She's 10 and loves it because "it's cute and small enough for her little hands", a great machine to teach on!
I'm looking for a green one now ;)
