Success! Wandered into HPB tonight and there was a new, shrink-wrapped copy of the ANH LE dvd. What luck! My circle is now complete. I got my three unopened LE dvds for $10 each, so I'm satiated. I'll never open them unless the UOT gets a proper, official release.
It's interesting how SW brings the OCD out in me. I wish I had that OT 2008 box with the slim cases. In fact, I wish I had bought a few copies when they were cheap last year to sell on ebay.
