I just listed my first batch of Ebay auctions. You can check them out here. This is just the tip of the iceberg as I've got literally boxes of comics to sell, both mainstream and alternative, so please check them out and check back here periodically for new links.
BTW, I used Ebay's Turbolister tool to create these auctions. It was my first time using this tool and I found it pretty helpful once I got the hang of it. If you're interested, you can download it here. It's free, and pretty easy to use.
