Does anyone know of a good price guide for foreign cards and promos?

I always check the completed auctions list on ebay. While it doesn't always represent the true value of the card, it at least shows you what people are buying them for... the street price if you will.

findmagiccards.com shows you what a bunch of different stores are selling them at.

not foreign cards, and promos are limited for FMC.

ebay seems good, but thats where I get them...
