I've owned an LE (sold it when made an offer I couldn't refuse). I then bought a Pro specifically to put a "Helen" kit on it and mod it out (just for fun). I made it the centerpeice for the TPF as you entered the hall. It got lots of attention and even the news focused on it when they did a story. I planned on selling it after the show, but honestly, I'm really enjoying it. I really don't miss the the lower playfield or cross over ramp (sorry Steve). I do miss the drop targets (especially the TNT drops). I would have missed the swinging bell, but that was easily remedied with the available swinging bell mod for the pros. Other add-on include 3D train, LEDs, flashing LED lightning bolts from Pinbits, metal apron, sideboard decals, shaker, cannon mod, plastic protectors, and some other things. Folks are right when they say the Pro plays faster. Without the drops, it can really fire the ball back at you.
Great game no matter what version to decide to get.
