Unfortunately, I can't steer you towards somebody who has the ceramic bulb holders. But just out of curiosity, where can you find a reflector? I tried a McGizmo MCR-18, and it didn't fit the head correctly (too small).
Good luck in your search!
I just checked and I do have the ceramic socket. I am not willing to sell the reflector that goes with the ceramic socket because I am using the reflector on a MiniMag with a P4 LED and I am quite content with the beam so you are out of luck on my reflector. BUT I do happen to have one of FM's turbo head which might solve your reflector issue as seen here: http://www.cpfmarketplace.com/mp/showthread.php?t=131575
