I quilt on a Nolting 18" with IS2K but years ago I used to quilt on a Nustyle 228. I have an owner's manual and a manual of the complete breakdown of the machine head of the Nustyle 228 if anyone needs it, I would be happy to copy and send it. I know they are quite difficult to come by. Some of the older machines are workhorses and actually easy to maintain; my Nustyle was.
