As was said earlier - you already have a fantastic 35mm lens - 35/1.2, so I see no need for a cron. As far as Mamiya - sounds cool, but If you want a Med. format camera ( and looks like you already have a few) I'd go for an SLR type, since you already have a Fuji 645 and TLRs. But really - best advice came from everyone who said - take that money and TRAVEL! You already have more than enough gear to get great photos - I know - I've seen your photos!
