I just got an email from NGC stating they have the numismedia F.M.V. price guide available for free to all members of Collectors Society (paid or free). You just go here
http://www.ngccoin.com/poplookup/index.asp and then click on "Census and Price Guide" link above and then once in there click on the coins you want to see prices for (MS or PF) and then once in the population page click on the "Numismedia Price Guide" link. I don't know how accurate it is but atleast its another resource that can be studied
