Oddly enough, "Lone Wolf and Cub" was the basis for the movie "Road to Perdition" (with Tom Hanks) which came out a couple of years ago.
The softcover X-Men collections I recommended are only $12.95 each... or you can do what I did when I was your age, and read them while standing in the stacks, without buying them. ;)
I don't even have to stand in the stacks. The bookstores kindly provide chairs.
Now I really am going to bed.
