Looking for a new engine

[The Monty]

Hey guys,
Well, my engine is leaking like a seive, and Ive pretty much given up.
Its going to be a head off job to fix, and I just cant be bothered, time wise and all the costs for the car have been spiralling a bit out of control.
ANYWAY,
long story short, its going to cost me $1200 to pull the head again and get it all fixed up or $395 for a new engine.
Thats the easy part.
The hard part is Im really chasing an AU XR6 HP engine.
If I cant find one, fine, so be it. If I can, awesome.
If anyone knows someone, or can find one somewhere, these are the prerequisites.
I need a cost, obviously.
It must have NO LEAKS.
It must have drove fine before I get it.

I dont care about KM's as long as its been serviced, doesnt leak and runs well.
Let me know what you can dig up.
Thanks
Josh
