Where to find rarity game guides besides DP

[acharris]

Hi all, I am looking for some rarity guides for various systems and the only one I have found is Digital Press. I am in the UK, so all the prices are in US Dollars and not GBP. Also their are no real magazines over here which show detailed prices of games, only retro gamer which is good, but is a more general guide of things. Any advice is appreciated. Thanks.
