Mike-
I think the Canon kit lens is the best way to go. It's a good deal, compensates for the digital crop factor of the small sensor, and it's got a good zoom range. An alternative is the Sigma 12-24mm lens. It's wider than the Canon kit lens. I'm not sure about the image quality. Think about if you like shooting wide or long more. Your decision should be based on cost, quality, and the type of picture you like to take.
