I have a Gammill Classic Plus (SR) without robotics. When I was researching, it was between Innova and Gammill and I got a good deal on this used machine and knew it's maintenance history. I've been very satisfied. I belong to a long arm guild and we had panel on the robotics--pros/cons, adding to our machines, etc. Seems that those with robotics seldom did any FMQ and those that did not start without robotics did not feel that they could/would learn FMQ. One thing that those that had robotics said was the switching from robotics to hand guided was not just flipping a switch, but involved little more than that and wasn't always timely. Those that custom quilted said that they did not use robotics as uber large shows have separate categories and their customers did not want the robotics. Several that used robotics only did E2E with them, although others said they would do some intensive programing (either on their own or with purchased designs) and have very elaborate designs. Bottomline from several of them is that the extra cost of the robotics pays off if you are doing many E2E quilts for customers. And one quilter/long arm tech said if you have the clientele to justify it, your best bet is to have 2 machines--one for FMQ and the other(he suggested used, with electronics needing repair cause when he installs robotics on a machine it usually results in rewiring anyway)setup to be working on overall designs at the same time. Bottomline for me was I do not have the customer base to justify the extra expense and love FMQ too much to give that up!
