I have the QueenQuilter18, the original version of Tin Lizzie. Only bell is stitch regulation. It's on a 10' Grace frame. I've had it almost a year now, but had problems with the frame in the beginning. It wasn't set up right, operator error on my part. Once I got it straightened out, I've done probably 40 quilts on it. She'll take any thread I throw at her. Tin Lizzie has been great with any support I've needed. She's a workhorse of a machine. Just went to a quilt show & test drove some other machines & am looking to upgrade. I really like the APQS & Handiquilters.
