They were made before there were Pro versions, there were just regular versions.

Differences (off the top of my head)

Costco Batman (same cabinet as a real game)
-No Joker reveal mech - Joker toy's just mounted on a bracket.
-No metal ramp, teeter bridge, or "Path of Gadgets" - this was replaced by one plastic ramp that goes to the left w/ plastics & lights to represent the gadgets.
-No Joker drop target
-One shade DMD instead of multiple shades of orange
-Always on Freeplay, no coin mech.

Ironman Classic
-New redesigned MDF cabinet screwed together Ikea style.
-No magnets
-No kickback
-All LED inserts
-Stronger slings to compensate for lack of magnet/kickback
-Easier rules
-Always on Freeplay, no coin mech.

Hey, didn't we meet a few years ago at Chicago Expo, or am I confusing you for someone else? That's where I played the Costco BDK! I think Stern brought it...it was next to an Avatar whitewood.
