U can buy a really good KISS on USA Ebay for peanuts. Worth nothing in the USA.
Prices in Australia are unrealistic and silly. I think it would be a mistake not buying from USA.
KISS machines from Euro sellers are usually flogged out and thats what most sellers in Aust have been trying to palm off for crazy money.
Go the USA machines from USA directly, or pay silly money for a flogged out hack. Its a hard decision.not lol 
I've been looking at the US market very closely for the past few months for a KISS for a customer.
You would be looking at min $1500 to $2500 for a 'flogged one' ie playfield wear, damaged cab, damaged backglass etc.. Most of the decent ones go for around $2800 to $4000 tops. Agree its not the silly prices they go for here, but you would still be looking around $1500+ on top of that landed. The trouble with the USA is getting the machine then shipped to a port (or airport) which will add an additional $200 to $300 on top.
