Ended up going with a CSF as I just could not resist the price.
I had a eBay birthday voucher(I think it was 10% off any item) to use so all up it only cost me $340 AUD shipped to my door. Makes you wonder how many the official Aussie seller in QLD actually sells when he wants $630 AUD shipped to your door for the same radiator.
I ordered it on the 21st of January and received it today, 2nd of February.
The box is a bit dirty, but the packaging inside is nice. So even the packaging is well designed by CSF which their website does advertise.
The radiator looks ok from what I can see. The welds are not super pretty like you would see from a robot but they are good.
It is very light, total package weight including the box is only 7.2kg.
The only thing I am a little disappointed in is the country of manufacture. Indonesia.
Then again the Koyo race radiators are also made in Indonesia. I guess that's how you make them cheap.
Eventually it will go into the car as well as a Whiteline swaybar at the same time.
17th/18th Feb would have been a good weekend to do it, but my helper(who will do more work than me

I don't think I will risk doing it the weekend after as the 1st supersprint is only a week after that.
So maybe early March to April it will happen before the 2nd supersprint round in May.
