I have been after a Contax 645 system and have been watching the market place. Good, complete systems in excellent condition are hard to find outside of eBay. The prices for these cameras tend to be quite high, but would anyone here consider this a fair deal? Can better be found? It's a perfect (boxed) condition, pretty complete and just across the border from me. Link to eBay sale of Contax 645 system Many thanks for your thoughts.
