True, my first concern would be the quality of my product in the hands of the general population. I have a tendency to screw things up myself.

I really like the "Ultimate Kit" idea of getting to design your own. Maybe you could even expand on that a bit where customers could make their own designs for their drums pads, either once they get say "blank" drum pads from your, or maybe something elaborate where they could upload images to you to put on pads (I have no idea if this is even possible, just an idea).
