Depends on which actor you want to see first, in which case the ones I'd recommend are:
Sean Connery - From Russia With Love
Roger Moore - For Your Eyes Only
Pearce Brosnan - Goldeneye
Daniel Craig - Casino Royale
George Lazenby only played Bond once, in On Her Majesty's Secret Service, so obviously pickin's are slim with him.

I'd probably start with the Daniel Craig ones, which are closest in sensibility to our modern movie habits. Some of the more classic Bond films are a little dated stylistically

My favorite is still From Russia With Love.
