pricing database

I found this website and thought I would pass it along;I don't know how accurate it is might it might give a relative idea for what gear is selling for. Leave any thoughts if you want.
Interesting site. It would take some work though as an item such as my Thiel CS1.6 speakers are listed more than once with different nomenclature.
Just did a quick check on a couple of my pieces and it seems to be on the high side.
