I think one pyrex mirror set cost around AuD 2700 coated/landed about 18 months ago to my recollection. Star Instruments will sell you professional grade 12" f9 optics from low expansion material for at least triple that (not the even higher end ion milled variety from Aries).
Field flattener lenses for my RC $550US. There are medium level cost European RC optic manufacturers - somewhere in Italy (possibly A&M) and in one of the new Czech states I think. There have been posts here about Chinese suppliers as well - not sure about their quality. Another Italian ATMer has a website which gives info on his 12" RC at
