I'm still looking. I've e-mailed IMSTO and GeekKeys primarily, but their responses have been glacial...a week to respond at best, I'm not even sure they read my last replies. I'm assuming SP is one of GeekKeys' suppliers. As I'm almost sure I wouldn't have any luck getting official authorization from Blizzard, I'm assuming my best bet is still IMSTO or some other Asia-based seller? I just want to get these damn keycaps made for my forum members, haha.
I'm basically looking at blue/gray PBT keycaps with black printing, and possibly black-coated ABS backlit keycaps.
Also /wave at MissAlaire.
