If you're just looking for the trilogy, go with this one. Includes the same disks as the 2010 version but with a new bonus disk and digital copies for the same price.

If you're willing to go a bit higher, this one is my latest. It's the same thing as above but includes a booklet and the animated series on DVD. It's the newer release of the flux capacitor packaged one, but cheaper. From the Amazon reviews, it looks like the flux capacitor box is nothing special so this version trumps it IMO.
