My first LA was a Bailey, and one big thing you have to remember is it's a rather slow machine. Even with stitch control, you can easily move faster than the machine can stitch.
When I bought mine, you could get a regulator (speed control) or pay more to get the stitch control (stitch speed depends on speed you are moving the machine). I think it was like another $600 add on. I did get a regulator with the Grace frame, but never used it (probably still in a box somewhere).
I'll agree that I think I'd also do better with a foot control then the regulator- but never could figure out how I'd deal with running the foot control while standing and moving around.
