Welcome azza, from a near neighbour in Melbourne.

If you're going to stick with MF then the Nikon film scanner is the ONLY way to go. I've never had one but I've seen the results and flatbeds just don't cut it in that price range.

Then again, if you can slow down to a more contemplative work rate, give 5x4 a go. If you're into landscape or archticture LF is the master.
