Hi Dave -
I'll put a plug in for the Elite's. For example, with the ROTJ Luke, the LE version uses a copper-like paint, while the elite uses real machined and polished copper. The materials are usually of higher quality, with more machine work and polish. There can also be whimsical touches which I like such as the green emitter crystal on the Luke ROTJ. The LE's are supposedly more meticulously accurate to the screen props, while the EE's take a few liberties to represent an idealized version. Some choose to view this as the version you would find in the "Real" Starwars universe. I'm having flashbacks to lessons in Greek philosophy.
