How expensive is the Samsung U800?

I have been looking for a good phone, and I recently saw a friend with one that I liked. I asked him what type of phone it was and he told me it was a Samsung U800. He said he really liked it and didn’t have anything bad to say about it, so I am thinking about getting one of these next time I buy a new phone, which should be pretty soon since mine is getting old. Can anyone tell me how much the Samsung U800 usually costs? And if there is anywhere I can get a really good deal on it?
