Is your 730 paid for ? If it is that's not that much of a deal. When I got my 440 in 2006 the 730 was in the high $6,000 range, so you'd be out about $7000 for the upgrade. I can get an 830 with the frame and the frame accessories for $12,500 in the Houston area and that's keeping the 440. What part of NC are you in ? We purchased two machines from A Different Touch in Chesapeake, VA, wonderful to deal with and I wish I was there now because they would give us a great deal.
