Thanks all for the comments.
I've been doing some calculations and if I build it like Vans intends it will cost about A$85K. That's complete, fly away, paint and all.
In the US they have no choices, as this is the way the kit was approved for their LSA class. We have some choices to save money here in Australia. We don't have to go with the Vans Avionics kit which is about A$16K. And there might be some savings on the power plant but I'll talk to Bert Flood about that.
I know $85K is a lot of money but for that you would have a pretty schmick glass cockpit aircraft and if your realistic about the actual cost of other aircraft choices it's fairly competative.
Thanks again for the advice.
