I have this machine with a stitch regulator and QBot and love it. There were a couple of issues (racing and tiny stitches ) but this was fixed by dusting off the sensor behind the wheel cover. The dealer where I bought was no help at all, but the makers now have several tutes on their website which help. I also needed to cut a small piece of fabric like a washer, to place in the bobbin casing to stop eyelashing.
The frame I bought with the machine is aluminium and not so happy with that, especially after I extended to 10ft, as the join causes problems when using manually, no issues using with the robot. Another dealer tells me I need steel tracks to make moving much easier, and I have yet to have this done.
If your TL is set up do insist on trying it out first, to make sure it works, and how easy it will be to manouver. They are not light-weight. Let us know if you buy, and there will always be someone here to help I"m sure.
