I have an older HQ Sixteen with Pro-stitcher. I love the computerized options and have taken a few classes on how to use the features. I still don't know everything that the pro-stitcher will do but I am willing to continue learning even at my old age of 73.
I totally agree with whoever said, your dealer is your best friend. I know I would never have gotten up to my level of quilting if it hadn't been for my dear dealers and our monthy LA club class.
