Host for eCommerce?

I want to sell products online and be able to have a shopping cart for users to be able to pay via credit card. What webhost have that kind of infrastructure? Should I go with eBay stores? Yahoo Small Business web hosting? What web host has a shopping cart features? I've heard good things about Dreamhost. Will that work for me? And what else do I need to get? I've also heard of oscommerce, but not sure what is involved. Please advise or point me to tutorials.
