Such a sad day, I'm truly shocked to hear the news. Like others I never really dealt with him much outside RTBB, but he was always one of the most professional and easy to deal with shop owned I've ever had the pleasure to deal with, pinball or not.
He was obviously well known outside Australia in the pinball community for his class as well, I recall when emailing Cliffy a while ago how highly he spoke of Greg (completely unsolicited too).
I echo cavey's sentiments about a tribute page and would be happy to donate toward any kind of tribute or memorial in his honour.
To quote Fish Tales: "Gone Fishin'. Leave a message". :(
