Well, there's always trade paperbacks. With Trades you get an entire story collected into one book. If you bought the comics as they came out at 3 bucks a pop, on an average of a 6 issue story arc, you'd be paying about 18 bucks, but with a trade you might pay about 10 - 15 bucks so you['d save anywhere from 3 - 8 bucks. And the X-Men have a lot of trades collecting key moments in they're history. X-Men: Phoenix saga, God Loves man kills, Age of Apocalypse, etc. There's also something called the Essentials. Which collects pretty much everything from the beginning waaay back in the 60's on through to modern times. (Eventually, I don't know where it's at now, possibly in the late 70's early 80's by now.) You get like 20 issues in one volume for like 14 bucks. The only problem is that it's in black and white and well, comics from the old days don't really translate well to today's sensibilities. I myself, find it very hard to read any comics from before the 80's. There was a shift during that time in which a lot of great writers and artist started to show up and really revolutionize the way comics were written. So, I can't recommend them myself, but if you're really into X-Men, and are willing to read the old stuff, the Essentials are there for you.
