I picked up the DualDisc version this morning from Target for $12.60 (after tax).
Shit is tight as hell.
I watched the DVD side when I got home. Pretty much shows where Juice and Paul grew up and gave a little bit of history about how they got together. It also has a video for Side 2 Side, which is tight as fuck.
I didn't see the Screwed and Chopped version, but I'll probably get that sometime in the future.
