Again, that's brilliant, thanks

I've settled on 20 inces by 10 inches. I know it's a little large for a single controller, but I figure the artwork would look gret large, it gives me something nice and big and not too intricate to build and I'll have loads of room inside to make the electricals look all pretty because I think I'll have a perspex bottom too......
I'll upload an accurate, scale button layout and if you've still got time to help out then great, if not then thanks so much for knocking it all up in the first place, it's made the difference between me having the idea, and actuall buying all the bits I need to do it :0
You're a legend!!
Lol, the saddest thing is, I've had an idea for my next stick now but I'm determined not to even do a pencil sketch of it untill this stick is done and dusted!!
