Here's another thought. Superformance. Comes as a complete roller and the guys at CTC will hook you up with a complied drive train of choice. You would have to contact Colin for details, but I am guessing with the Aussie $ on the high, prices may be in the high quality 'built for you' category.
In any case, Colin is a good bloke and will give you a straight answer.
