I don't know what this machine costs new. But It seems high. You have a Juki now this has the same neck heigth as your Juki. This machine is made by tin Lizzie. Because of the neck heigth, I'm guessing it is a stretch machine. It doesn't matter how long the neck is if as you roll the quilt it is hitting on the top and bottom. Also the frame needs to be adjusted each time you roll to accomidate for the increased size of the quilt roll.
I know that the Handi Quilter Avante doesn't have these issues and is less money. Just a thought.
