haha, okay lets do an educated guess.
Gimbal unit 35$
Shapeway print, 100$
PCB 20$-30$(depends a little on what fab is used, can also be done for peanuts manually )
Aluminium, bearing, springs and paint. 15$
And then there's the PC connection. One could do it for cheap with a teensy/arduino clone(3$), but I think you used a Bodner board?
Add in transportation costs and you are looking at about 200$ I suppose? I doubt anyone here would be willing to shelf over that much money.
Although I've taken some large margins on parts, sourceing it in China can save considerable.
