We have bought several machines from them. We love vintage machines. Actually my DH B-day was yesterday, and the one I bought him arrived. A 1964 New Home (Janome) purrs like kitten. Beautiful machine, he named her "Ivy". She is a pretty 2 toned green. He was all excited, he told his pals on the gun forum and like I predicted the boys were excited to tell about their machines.
We also collect old metal toy sewing machines mostly hand crank, we've bought 10 from them in the last 2-3 months. We even found a Betsy Ross electric one in the case that runs and it looks like our hand crank Betsy Ross. Our 5yr old DGD has used it, and loves it.
The only bad thing about the Goodwill auctions is the same problem as this site ADDICTIVE!...
