What is the best starter-spaghetti for non-spaghetti friends?

The only problem I see in starting with For a Few Dollars More is that for newcomers it may seem like introducing someone to the Star Wars Trilogy by first showing them The Empire Strikes Back. Since the Dollars films all work as stand alone films I don’t think this is a real problem, however. Still, I suppose in an ideal world I would just do a triple feature and save Django for a rainy day.
