I just asked him to burn 4 x EPROMS to fix a couple of CPS1 boards the other day, the guy's name is Stephan Suys and he has very helpful, very knowledgeable and very quick to respond.
The EPROMS haven't actually arrived yet (what with me being on the far side of the world and all) but from what I've seen so far he seems like a damn good guy.
Will let you know when they get here.
