Quoted from FlippyD:The term "price gouging" usually applies to basic goods and necessities. If you try to price gouge a pinball machine you just get laughed at or people walk away. If someone has enough money and not enough brains to buy a nearly immaculate machine at the highest price possible, then that's their own damn fault.
Also, is there a huge difference between the LE and Premium from a game play perspective? Seems to me that LE buyers in general are more on the "pinball is a collectible" side so would be accustomed with the economics of collectibles. But if you're just in it for the game, it seems like there's no shortage of Premiums available.
I also think speculatively buying LE's can be a dangerous game to play (e.g., WWE LE).
