Just wanting to see if theres any cheaper range kits out there for sale? Like BB kits or BB realborn kits?
Look on eBay for sellers of BB kits in your country. I’m in the UK and found a few sellers for BB kits on eBay. They are reasonably priced compared to getting them from America and you might find the same. I just searched for a specific BB kit and then looked at the sellers.
You might also want to join some Facebook groups that are specifically for selling kits in Australia
