Yes, I am the sewing machine rescue squad in our area.
My DH picked up a Pfaff 130 in a cabinet...both machine and cabinet are in pristine condition. He got these at an auction for $5. He said he was the only one who bid! I use it in the extra bedroom for a bedside table.
Then on a service call (he does heating and A/C repair) a customer gave him a Singer 15 in a cabinet (made in 1946 according to the serial number). I cleaned and oiled it and it purrs like a kitten now. I use it in my entryway for a table.
At the same place he was given a pale green Singer in a cabinet...don't remember the model, etc...prob. from the 60's. I cleaned and oiled it and gave it to DDIL because she wanted it!
This past Christmas we had some friends over and they brought me a newer (prob. 80's model because the body was metal) Brother machine in a cabinet that they had rescued from someone's basement. My friend doesn't sew so they brought this to me. I cleaned and oiled it and sold it this past weekend on our yardsale.
A couple years ago I found one at a yardsale for $10...an old metal Necchi, prob. from the 60's. After cleaning and oiling it I gave it to my friend that needed one!
I don't have room to keep many machines, so I try to pass them on to people who want/need them.
Personally, I use a Viking Platinum 775 for my sewing and a Viking Scandinavia 400 for embroidery. I keep these in my small sewing room along with a serger. I don't have room in my sewing room for the older machines, too, or else I would prob. use them for some sewing, too.
I am currently looking for a FW to use for classes and travel. I know if I wait long enough either I or DH will find one quite reasonable around here.
