On the Goodwill Auction site (page 8 under sewing machines) there is a KH-910 for sale for $7.99. Only problem is it must be picked up somewhere in Central Texas. Cannot be shipped. From the pictures it looks to be in good condition.
wow, that's a good heads up for someone
The 910 is quite old, and there is a chance the electronics in it will not be in working condition. Goodwill doesn't usually check these types of items out to see if they work or not, other than possibly turning them on for small appliances, etc. Even if the electronics are kaput, it can still be used as a manual standard-gauge knitter, and as long as the main carriage is included. Someone might get lucky though, and get a functioning machine practically free.
It can also be updated with a AYAB board.
