Thanks for the link. You're a prince!I purchased this one:

It is a regular Blu-Ray in a simple black keepcase -- no booklet. Also I am aware of the fact that there are true experts on this forum with knowledge about transfers that eclipses my meager knowledge. But my enthusiasm about finally having a wide-screen, anamorphic, decent transfer caused me to post. If you've suffered through, for example, a previous Italian DVD release of the film you know what I mean!
