I was torn when I bought mine but money was an issue so I went with a pro. I have a good amount of time on a pro and then a couple weeks ago I got to play an LE. I prefer the pro.

I really didn't like the randomness of the magna slings, the ecto goggles were ok, but nothing that would make me spend the extra money. I didn't like the height of the left ramp and the wild air balls it created. The pro still has air balls but nothing like that. I don't know if or what the difference is in the light show honestly. The pro has the RGB color changing lights and I think its done great. Not sure if there was more added to the LE.

Slimer coming up/down instead of left/right was really another non-issue for me. If I did it again I would go with a pro again and save the extra money for another machine.
