I have the little gracie II frame which Bailey's sell as a 'deal'...
I do not have the stitch regulator and see no need to get one -
you do have to remember that the machine runs slower that a high priced long arm and move the machine accordingly
I did a few 'practice' pieces then a quilt...
I've done quite a few since then -
I wouldn't call it "cobbled together"
call and talk to Mr. Bailey - he's there on Tuesdays on (not there on Mondays) - he will be happy to answer any questions you have..
