It's a pretty open-ended question. Are you looking for the best figure of everything? Are you looking to display in a showcase or maybe do mini-dioramas? Do you have a fav. movie of the 6 films? Are you willing to do minor tweaks to a figure? Could get expensive. Hasbro has a lot of great figures that need just a little help. Dooku and the droids are widely considered above average for them. Sideshow nailed ANH Kenobi and Luke/Han Stormtroopers. If you do a search on individual figure threads here, you'll find the pro's and cons. A perfect example is the SS Vader. Plus's-Best in ANH duds by a country mile, Con's-generally considered too tall and many have said the helmet sits high and doesn't flair out enough in back. I think you'll get a lot of "Look around and see what
you like best". There isn't alot that's pure crap, and even those may be fine by you. It's a very subjective line, in a good way. Makes for some fun debates
