I don't think there are too many floating around anymore. Craig has been out of them in XML for quite awhile. Still has the XPG version though. I have been buying Matt's 10mm copper MCPCB and turning them down when I need something smaller. It's a PIA but a man has got to do what he's got to do! John Wayne BTW.
Illumination supply is out and I have asked Derek, and sadly he has none. I like the design of these 8mm boards the best, now if they were only copper.
