I use vision imagelab in redfern, sydney and they usually have a 2 hour turnaround w' dip'n'dunk. I was once lucky enough to drop off my film, venture to sydney uni for a 1 hour lecture and return to find my films ready. A quick turnaround for me at least is a luxury but needless to say the quality control must be there, which with vision i find to be very good.
i'm very much preaching to the converted but i do hope e6 stays alive in some shape or form.
btw Stephen, i just noticed you operate your lab in sydney as well. where exactly are you located?
