Just finished downloading Moth3r's Pal Transfer of Empire and it's f'king awesome!
I'm from the UK so Pal is my native colour system so I guess that gives it an edge in compatibility/quality in regards to playback equipment.
I own copies of 80's VHS, 1997 special edition VHS and the 2004 DVD's. This probably isn't the right attitude to have, but i feel i've thrown enough money at lucas and his subordinates for them to be happy. If the original versions are not going to be made available commercially in digital format i haven't got a problem owning bootlegs.
Most of, if not all of the transfers were created by fans for fans, and have been non-profit making. The projects are not out there to screw Lucas but preserve a heritage which we shouldn't be denied of.
The law is the law though ofcourse so it's your discretion.
