Have to agree with my brother on this one (both about what he said and about not making it through the first post...I'll work on that!).
The PC forum has always been a cesspool of market manipulation (in whatever direction benefits the currently powerful "gurus") and has never born much resemblance to what is actually possible.
I think that information about actual sales of similar items (price, when the sale was made) is useful, but only for loose reference. I suppose that information about non-sales of similar items (e.g., "One of those has been for sale on legacy for XXXe for the last 2 weeks and nobody's taken it.") is also useful.
Unfortunately, what often happen on PC threads is that people don't talk in facts. They talk in terms of their own beliefs about what an item should be worth. That is most often pointless. And sometimes they go one step further and argue about whose version of "should" is right. That is useless. If we are going to say that there is a market for an item, then there very well may also be segments to that market -- some potential customers who are only willing to pay a certain amount and other potential customers that may be willing to pay much more. Even the most benevolent PCer may only be familiar with one or another segment of the market.
That is why, IMO, the only useful info that can come from a PC thread is factual information about recent (non-)sales of similar items. But even that needs to be taken with a large grain of salt. That information is just as much about the seller's skill and determination as it is about the value of an item on the market.
