I'm in Brisbane. Prolab did my first set of 8 transparencies (a while ago now so was only $10 a sheet!). That convinced me right there that I had to do my own E6.
It's REALLY easy. I picked up an old CPE for under $300. It's done over 200 sheets now. I've got it down to around $1.40 a sheet. And it is the best feeling ever doing it yourself.
Prolab don't drum scan but they do have a very good flat bed and a good operator. My first exhibition was scanned and printed there and they did a great a job. 52" Fujiflex prints are something to see. But VERY expensive to make, mount and frame.
If you have questions on DIY E6 I'm happy to help. If you are in Brisbane you can even drop around and check out my set-up. You bring the beer....
