16 Dollars for the 2-disc Special Edition of From Dusk Till Dawn IS a good price.
You get an awesome movie in good quality, with an AWESOME audio commentary, lots of making-of documentaries and deleted scenes and much more. PLUS "Full tilt boogie" - the full documentary.
THAT is a greaet package.
NEGATIVE ASPECT: the DVD is non-anamorphic (the Australian, German and UK editions are). But that's only annoying if you call a 16:9 display your own.
