ThinkGeek offers the Arcadie Desktop Arcade for iPhone / iPod, model no. CE4280, for $24.99 with free shipping. That's $6 under our October mention and a buck under the lowest total price we could find for any similar gaming cabinet. (Most merchants charge $50 or more for such a cabinet.) It fits the iPhone 3GS, 4, and 4S, as well as the 3rd-generation iPod touch and all newer models. It features a joystick and two buttons to control free arcade game apps.
