Douglas,
I'm not aware of anything current: there's a list out there that like 10 years old, so meaningless.
Frankly, I'd consider eBay as a great resource to see what gear is actually going for.  You can search completed auctions to see what people have bid recently.
Also, there's tons of used retailers on the web who list prices: try  
www.ugbm.com   or  
www.musicgoround.com   to see what they're asking (although they may not actually be selling items at these prices).
