At that price I would rather grab a Tom Bihn Small Cafe Bag for $50:

Tom makes GREAT bags, pays a living wage and runs a very ethical ship...best CS around too. There was some discussion early on after the Kindle release about a carrier specific to the Kindle (or other ebook reader for that matter) but I never read it went anywhere. But this Small Cafe bag would more than fit the bill.
