The topic that underlies a lot of this and other discussions is that as prices rise, you have collectors that can afford the new pins and those that have been priced out of the market. A lot of what people consider A list titles (90's B/W) came when production was limited. Those games in a lot of cases have been restored and the combination of scarcity and restoration allow them to command a higher price. Rich guys want these pieces as trophies while people priced out of the market and want those games are upset. It happens in every hobby. From my own experience, I see prices rising and that is not going to change. In my case, I am trying to decide if I want to go spend the money on a nice ToM (my favorite game from back in the day) or take that same money and buy something NIB like Houdini.
Just remember: Whether you are a rich guy or priced out of the market, neither side is "right" or "wrong". You just have different motivations and priorities.
