I went with the LED Pro because I agree with the OP; they may be everywhere but people are NOT selling them off like they are RFMs or STLE/Pros. ACDC is NOT a popular game being sold; it is being held tightly because people realize it is a great game.
I bought the LED Pro because it has the moving bell, and I added the 3D train on the left ramp. That - for me - made it "close enough" to being a premium model.
Yeah, it's Stern's most produced game (#s to prove this?) and they're EVERYWHERE - but people are not mass selling them.
