G-Man,
I don't disagree at all with your assumptions. However, when the price for certain items rise (or fall), and continue to do so, it is a "market trend". Those old speed planes brought next to nothing not too long ago on da bay. But, collectors got wind, or caught an interest in them, and now the prices are much higher overall. Sadly, it happens to just about everything. Sentiment, nostalgia, even egos, drive the prices for "collector" items.
Yes, if someone wants it, and has a fat wallet, they will pay whatever they need to because they can. No argument, no complaints.........
