Fran, I like a lot of things about the G70, particularly the live sound and the styles. I've found a couple of great guitars that suit my style. If only it wasn't so big and heavy I would consider getting one.
My plan is still to get a Korg PA800 and at least give it a trial.
As far as a patent, I don't believe it would be possible using the Ultimate Support parts. It probably would be possible to start from scratch and develop simiar or better components, but that would take a lot of startup money.
If I can build something like this it would seem reasonable for an established company to make something even better. We need LIGHT weight, versatility, and quick setup time. "My" stand does all that.
