I agree with ckcowl. I had a Brother 1500 on a grace frame. It just takes a little getting used to controlling your "pedal". The Grace frame came with a bed that the machine sat on and the pedal connected to a hand-squeezer for the speed. I used that set-up for 9 years...but I also had the panto-boards (grooved board that the metal stylus fit into to make designs). The only thing I might have purchased would have been the upgraded machine bed thingie (the thing the machine sits on)....it supposedly makes it easier to maneuver the machine into curves, diagonals, etc.
In the meantime, my husband purchased me an Innova set up.....so I'm in Heaven. But, I've kept my PS1500 for sewing and the frame/panto-boards in case anyone wants to purchase it.
Whatever you do, practice, practice, practice. I do remember getting so frustrated at first......
