what country should we choose?

For those of you that have adopted from Columbia, what agency are you using? I thought Columbia was closed or slow moving right now... what is the story? We might be interested in going there for our son. Can you tell me anything about the process, cost, travel, etc.? My husband and I are considering adopting from Somoa, in the Pacific Islands, but haven't made up our minds yet. We currently have a five yr old daughter who was born in Russia and looks just like us. Because of relatives with native american and polynesian/hawaiian background, we feel like we can go just about anywere and the child would fit in with our family.
