No Country: SD to HD Upgrade Value?

[BanjoBob]

Hello everyone!

My very post here, but I've been an avid lurker for quite awhile.

I finally made the transition (or I should say my fiancee finally let me) from a 720p/1080i home theater TV setup to a brand new Panny 50PZ700U + Panny BD30 player configuration.

I am a religious movie buff and have an SD collection of approximately 1300 DVDs. Today we snagged No Country For Old Men our 2nd BD (Apocalypto was the first; one of her faves and a flick we didn't already have in our SD library) after having researched reviews saying the transfer and AQ are top-notch.

However, I'm still a bit hesitant to crack it open since, as can be assumed, I also purchased the SD DVD a couple of weeks back. Can anyone who has both formats or seen both give some sort of feedback/opinion as to whether the upgrade is worth it?. Or does the SD DVD suffice?

I've "double-dipped" SD DVDs before and have usually offloaded the inferior copy to friends and family, so I could get rid of the SD NCFOM, but it's the loss of the initial $15 and the $9 extra cost of the new disc that gives me pause.

Any help much appreciated. Got to put one of these badboys in here
