I have been trained..and also used the Pilot system that ABM sells for the Innova ( I own an Innova as well) and teh pilot system is relaly user friendly and it does just about anything you want it to do..records your own personal designs...can plan out your whole quilt, add any designs, comes with 1000's of designs ect.
It is a great system.
However...I don't like computer quilting unless you are going to just use it for all over designs.
For me it takes much more work to plan the quilt in the computer system then If I just mastered the technique myself..and had a few flaws here and there. That is just me though. I have to ask myself if I would get 10000$ worth of use out of it?
