Anyone know a good price guide site for comics that is up to date? I have several from the early 80's to around 2000 or later. Some are in excellent condition and others are decent. I am also aware that a lot of people buy/bought X-Men, Wolverine, etc.. So if I ever wanted to sell them it would be hard to find a buyer. But I just want to know how much they are worth... any help for a site is appreciated.
