Hi Mark. It really depends on what you need a new camera for.

Starting to build a new system with the FD and/or NFD lenses might take some time and could eventually cost you quite a lot because certain lenses are so popular and often hard to find cheap even in the auctions.
So, you can certainly get a backup body and more lenses for your F3 for the money you will spend. That way you will be more comfortable with what you use mainly.
