lol i was just about to post exactly that. I used to go to one fair or another most weekends, Bowlers being my favourite. (I sold home built PCs for a few years between university and getting my proper job, mst have been 1997/98
I sold some right dross at the start (cryrix processors, with a vxpro motherboard and a sparkle S3 trio or virge)... (i got better at picking better parts as time went on - the TXpro was heaps better than the VXpro for like a 5er more)
The fairs were decent back in the day but even then they were starting to fall off.
I did get sold a fake pentium 2 processor from a dodgy small company who traded there who are now massive - wont post their name as they are a rival - and they refused to refund me when i went back to the following show with proof................ and also same some hilarious police chases with them running after people selling pirated software out of suitcases.
