In another life, I collect vintage sewing machines. Fools on eBay list $25 machines for $100,$200,$300 or more. There's one machine that a co-collector tells me has been on eBay for SEVEN YEARS.
OTOH, a Singer Featherweight recently sold for $1,200!!!
At *least* 2 times overpriced, more like 3, possibly even 4!
Like I said, 2 kinds of idiots...
