Sorry can't help either...
Up here in QLD, CR, Homebush, Dax, Robnell, SPF etc are pretty rare. We have them...but you would be lucky to see them.
I've seen them all and in my experience I wouldn't say one is any better than the others when it comes to recommending kits to people. Different cars suit different people...they all offer something different and that's great. We wouldn't all want to be driving around the exact same cobras, be a bit boring.
Most of the cars(regular) in club up here in QLD are DRB & Harrison, and some old RMC's.
Owners of DRB(Peter Ransome) & Harrison(Warrick Harrison) have pretty strong ties with club and attend most social & race meets. They are also the first people to jump in and help fellow club members, lending equipment, services etc if things go wrong. With that sort of support & commitment it's pretty hard for most people up here to choose anything else.
Even with my DRB GT40, Warrick is keen to help. He is happy to help with any type of kit, he is just that sort of guy.
I'm a little biassed towards Warrick though, having bought two Cobra kits from him.
So my recommendation is to first find kit that suits you and then make sure they have service to back you up. And go along to club meets etc and ask plenty of questions. So you off to a good start there.
It certainly makes things easier if you go with a local product.
