For me it would probably be the fourth time i bought the trilogy if such a thing occurred, 1. being the 2004 fullscreen dvds (I was very young at the time, and while i did notice the changes between the rented 1995 fullscreen vhs tapes, I didn't care at the time. All that mattered was that I owned the star wars trilogy. Though for a couple years I thought the 1997 and 2004 SE were the same, with the Jabba shot at the trailer being a prototype or something.) , 2. being the 2006 widescreen dvds (which I got recently), and 3. being the 2011 blu-rays (mainly for the OT deleted scenes)
