i bought a 99K with table at a yard sale for $10.
i bought a new belt, a new o-ring and a new throat plate from lostn51 for an additional $25 + shipping.
so for $35.00 + about another buck or two shipping, i have a 99K all ready to roll, with some attachments and manual.
i can tell you, IT IS DEFINITELY NOT A FEATHERWEIGHT. IT IS A HORSEWEIGHT.
i don't think that's a special price by any means. they show up on craigslist and ebay frequently. even goodwill has a website where they show up all the time.
this is the link for goodwill:

right now there are a few vintage machines available and even with shipping are good deals. register to get on their mailing list.
