A very helpful friend of mine has his birthday coming up. I've heard him mention a couple times that he'd like to own the Watchmen comic series (that's the one being made as a movie by the Dawn remake guy, right?), so I've decided to get him that. I'm willing to spend more than for usual friend gifts, since he's helped me out with various tedious things (such as moving

) and I feel I owe him that.

Thing is, I know nothing about comics. I'm not familiar with the whole terminology. I've been looking at sites like amazon.com, and from the descriptions (filled with terms such as "trade paperback" which mean as much to me as if they were written in ancient Greek) I can't make out whether the editions they're selling contain the full series.

So my question is this : could any of you fine folks point out to me which edition of Watchmen I could buy (preferably from some big reputable site such as amazon) so that my friend has the whole series? I know there's some thing called the Ultimate Edition or something, which costs a few hundred bucks, but hopefully I can buy another edition for a less insane price (I owe him, but not THAT much!).

Thank you very much in advance!!
