For the price of the Nolting package (with frame and stitch regulator) you should consider an Innova. IMHO you get a lot more bang for the buck. But you may not have a dealer near by. I love my Innova and I have yet to come across a dissatisfied Innova owner. We all LOVE our machines.
Made in the USA (Texas) and manufactures all their own add ons so everything works together exactly the way it should. Even their frame is custom to their machine.
