I have a Gammill Vision 18/8 and love it. I am not familiar with the Pfaff so unfortunately, I can't help you with that. There is a learning curve with any longarm, but the few problems that I have had, the technicians at Linda's Electric Quilters have walked me through the solutions by phone. I have been very pleased with the support. Gammill has been around for a long time and has a very good reputation.
