Its getting difficult these days Scott, I'd say mostly to the containers coming in starting to dry up.
Most of the importers are not really selling 'project' games straight out of the container doors. Ignore the eBay pricing.
Keep checking Gumtree for the odd bargain (before dealers / dealers lackies snap them up from under you) and maybe try Oscar (Pinball Memories). I'm not aware of anyone else in Vic who is publicly selling projects.
Depending on the title, I'd expect to pay anywhere between $2000 upwards.
I know of a Time Warp, Counterforce and SWEP1 a member was selling in Vic. These are well past 'project' stage and are A1 machines, but not eBay dealer pricing.
