Some of us have compiled product lists, however, as far as I know there has never been an official list put out so the accuracy of someones lists may be questionable. For myself, I put together my list based on what I already own, have seen and from other peoples lists.
As far as what is a good price, I think that is subjective as well. Some people won't ever pay more than the original selling price for an item, some people will pay more for rare items. I have paid a lot for items some would think I was crazy for, on the other hand, others have paid a great deal for items that I find crazy. You have to find your own "threshold of pain".
Sorry there isn't a definitive answer:/
