I've been reading about Bridgestone bicycles on Sheldon Brown's webpage: http://www.sheldonbrown.com/bridgestone/
It sounds as if the Grant Petersen-era Bridgestones are great bikes, and I'm thinking of trying to find one. I've heard, however, that Bridgestones are prone to break at the headtube. Is this true?
Also, what would be a fair price for, say, an RB-1 or RB-2 in good condition?
