The Singer 99--it goes on ebay for about $50 or less. It is so user friendly, easy to clean, maintain, and small enough to tuck under a table when not used. Lots of parts and attachments are available for it, also. Or its plain version: the Spartan. Add your own decals or stickers to brighten it up. I got a Singer 99 this weekend at a yard sale for $35.
I know the featherweight is nice, but very expensive. If you are not going to be lugging the machine around, save the money-------------for fabric!
