Okay, I'll chuck in my Aussie 2c worth too
... I've got a featherweight and a 99K. They are both in the most beautiful condition and I would say that the 99 has a better straight stitch (by the finest lint fibre) but the Featherweight is stupendously adorable. Have you considered buying a 201?
I just bought my 99K for $60 and it is absolutely pristine, in a gorgeous bentwood case with knee control... and Mike's most recent 201 he got for $10 (which is ridiculous) but you should be able to get a really nice one for $60 if you wait, even in WA. I think he's right that you won't get a featherweight for less than $250. Maybe $200 if you're really really lucky. I say that because I got my 222K for $300 (ish) and they usually go for a lot more... so the 'finds' are out there
Hope this helps a little!
