x-men all the way. i had some where around a thousand books at one point, nearly all marvel. still have original #1 night stalkers (along with #s 2,4,5&6) and had a 1964 #4 x-men, which was one of my highest prize. i have nearly all the marvel movies on dvd or vhs, and actually wacth them quite often. now there are a few exceptions to the rule though, from dc, i always collected batman. i can't remember who did the tarzan line but i had a ton of those too. as well as a lesser known line called "the warlord". the warlord was about a soldier who was transported to a barbarian sword and sorcery type world, where he fought for survival with his trusty .357 magnum. i must remark that although i love the blade movies, they really scr#wed the night stalkers up. king is still a vampire in the books, and frank drake is a member of the stalkers, as he is the great grandson of dracula and not dracula himself. all in all i am very impressed with the most of the adaptions though. i haven't seen electra yet and of course i am chomping at the bit to go see X3 next week.
LasT year, I sold a lot of old comics on Ebay. I made out pretty well. Comic price guides don't necessarily mean anything because U have to find a buyer for that price. But, look up some of your comics on Ebay and see what they are going for. I split up mine into batches. Some batches went for $90 or more. Guess there was an issue or two that someoen wanted
U can also mail out the comics to the buyer Media Rate - a very cheap postal rate. U can still insure it to.
