I'd like to pick this up. Is it still in print? Also, I commonly see two releases of the film at the used stores, one of them belonging to a Hitchcock boxed set. Which is the better release?

Yes, it's still in print, and as far as I know, the only difference is the cover art.

Used is cool (I do it often), but if you want new you can pick up this great film for less than $13.99 shipped at DDD:

Psycho

Note it's non-anamorphic.

I saw it at Wal-Mart the other day. If you don't do online try there.
