There is one on Craigslist near me for $700. Is this a good deal? I don't know anything about them.

Check ebay for prices.

I tried eBay. They didn't have this model listed. I'll keep looking. Thank you.

There is a buy-it-now on ebay for $398 plus skipping. Anyone tried this for free motion sewing? Claims 11" arm space, which would be really nice!

I found it to be an industrial machine. It has a pulley to be hooked a motor on table stand.
