First off, let me say, this is available in full on Hulu. If you want to permanently add this to your cloud, this seems like a decent price. Each season has 24 episodes, which are priced at $1.99 each.

edit: Just realized seasons 4 through 6 aren’t available digitally (or to watch on Hulu). Perhaps not the best solution for owning the show.
