I'd check out these sites. I'm planning to resurrect an old, broken CM rapid so I've been digging online quite a lot.

I need PCB versions of:
2x of MX Browns, Clears (MX Clears), Blacks, Greens, and Greys as well as the 4x Gateron Clears mentioned above. How much would it cost?
Also do you know where I can purchase transparent non frosted polycarbonate keycaps for R4?
For more keyboard stuff you might also want to check out geekhack and deskthority.
