Can anyone recomend a place to get parts in Brisbane. i.e Two yello flipers and some new rubbers. Is E-bay a suckers bet?

You'll end up paying much more for consumable pinball parts on ebay.  Handy sometimes for the hard to get s/h bit or assembly.

I get all my parts from RTBB (rubbers, globes, flipper kits, ramps and LED's).  Excellent service and price.
