I just bought some Formula RX brakes from this guy on Ebay.

He is based in France, and delivery of my brakes took less than a week.
Send him an e-mail and see if he can help you out.
He has been GREAT to deal with. I lost the pivot bold for the lever first ride (must have been loose from the factory). Sent Nicholas an email yesterday morning explaining to him what had happened and he sent though a replacement that night free of charge. Needless to say I am very happy with the level of customer service.
Considering how strong the AUD is again the EURO at the moment, this would also be the cheapest option.
I got my RX brakes F & R including rotors and all mounting equiptment for ~$320 AUD.
CRC charges ~$177AUD for lever/hose/caliper ONLY.
