Best Price for 'Senna' on Blu-Ray ?

[Midnight Rambler]

The bio of Ayrton Senna releases in the U.S. on ~ 12/20/11.

Has anyone seen any good deals on this yet ? Best I'm finding is $31 for the std. blu-ray. There are at least (2) other versions, incl. a $500-600 ultimate with a diecast of a Senna car, etc. The mid-level version, $50-60, I'm unsure as to what it includes ???

Equally confusing, I originally read that this movie was around 150-160 min. in length, yet this release states 105 min. or thereabouts. Anybody know what happened ... movie was re-edited, missing "extras", etc. ?

Thanks for any help ...
