Here's another yahoo group - PfaffHobbyGrandQuilter . It's not as busy as the homequiltingsystem group but there might be some good info there, too. It's described as " for those who either own or are interested in the 9" Pfaff Hobby Grand Quilter, 9" Viking Mega Quilter, Janome 1600P, Pfaff Grand Quilter 18.8, Viking Mega Quilter 18x8, Inspira frame(original), Next Generation frame, Imperial frame by Inspira and QBot(frame mounted computer robot)."
Have fun!! :-)
