Quoted from ASOA:When is it not ok to turn a profit in selling a pinball machine that is valuable? If you could sell a game for a large profit would you do it?
Definition:
Price gouging is a pejorative term referring to when a seller spikes the prices of goods, services or commodities to a level much higher than is considered reasonable or fair, and is considered exploitative, potentially to an unethical extent.
It seems a lot of people are basing their opinions off mostly Maiden LE since that's the flavor of the month and their concerns for the quick flip practice, but realistically addressing the OP's question, anyone that feels selling for a profit is unethical (I consider this at any point in the lifetime of the pin), are you applying this across the board to used games that are currently selling for well above the original MSRP? Because if so, the majority of anything on the marketplace will fall into this category.
Just looking through the first 2 pages on the marketplace from current distributors and 3rd party sellers, the following rough percentage price increases/decreases are as follows.

Iron Maiden LE is 53% basing it off the highest pin for sale which is $13,500. The one in which everyone is blowing up the thread is at 34%.
