I have not been to the Melbourne market but I suspect it is a bit bigger and better than Sydney. I find a lot of the bodies and lens overpriced compared to eBay and other channels. Phil Ramsden (treasurer of the Sydney fair) had the proceeds of a deceased estate and some good condition Topcons went early. There was one guy trying to sell some well worn darkroon gear including two old Leitz enlargers. For $25 I picked up 5 Kodak stand developing tanks with floating lids and a variety of frames and holders for different film sizes. Might have a bit of fun with these in the next few months. Also picked up about $100 worth of Anti Newton glass for $3 from the same guy and a portable CD player for $5!
All up, spent less than $50 including tea and chocolate mini-muffins... a very restrained outing....
