Selling Comics

After sorting and deciding which ones are staying and which are going, what would be the easiest way to sell comic books? Most are from the last 10 years with a few from 1992. Mostly X Men titles, some transformers and a few other types.

Ebay could be an option but is there a site where you can just list everything and people buy what they want like Amazon? It would be nice to get our computer room back.

Also, in the same vein, Magic Cards :/
