Fullmetal Alchemist PS2 Games

Hey there. I have someone wanting to buy the 2 Fullmetal Alchemist PS2 games (english versions) but I'm looking online, and the only listings I'm seeing are for people selling the Import copies of them.

Does anyone know how much value the two games have English version wise?

They're called Fullmetal Alchemist and the Broken Angel (complete) and Fullmetal Alchemist 2: Curse of the Crimson Elixir (complete with bonus disc)

You can find USED (very good condition or like new) at amazon.com around $10 - $15 shipped
