Me personally, I made an anti-panda. Not that I have anything against your Panda.
I took an M6 Classic in black chrome, and put a silver chrome M3 winding lever and a few M6 chrome spare parts on it. I think it's like NicoM says, the premium is roughly equal to the cost of buying and replacing a few parts on the camera. If you like the look of them, which I do, then go for it.
