So, $2k extra for the topper (which only cost $400 less than a year ago)?
Might be the best topper Stern has made, but c'mon man!
Hell, if someone wants mine I might let it go for only $1500! Installed since last June, and typically have the animatronics stuff disabled through settings when playing alone, so the "wear" items have minimal use. I'll include the box, manual, and all packing materials FOR FREE and will even don cotton gloves as I meticulously and lovingly prepare it for its journey to you!
In any case, it's hard to imagine coughing up $7500 for a Pro when none of the "mods" actually do anything to enhance gameplay, especially given that $7.5k (probably less, if you are nice to your distro) will buy a NIB Premium AND let you enjoy that "new pin" smell for a few weeks. (With some Stern games, the gameplay delta between the Pro and Prem/LE isn't enough to justify the increased cost, but on this title the Prem/LE really does offer meaningful upgrades.)
