Hi there, I'm up in Perth and have an Extra 230 for sale on AFORS which might be of interest, a bit higher than your budget but if you can get to Mid 70's I'd be there to talk. Just back from having a 6 year prop overhaul (LPIP) and its an awesome machine to fly.

I also know of a chap that might be interested in a share if that would help you get to a 3rd member? I had a Pitts S1C previously and the Extra is a big step up in performance with 230hp and a much more slippery airframe. I bought the aircraft last spring from Paul GIbbs who I know well but I'm looking for something with 2 seats now and to be honest the Extra is far more of an aircraft than I really need aerobatics wise, Super D is probably more suited to my standard of (shoddy) Aeros.
Happy to let you have a look around her if you are up Perth way?
