Get this Sony Speaker Dock for iPod and iPhone (model RDP-M7iP) for $49 plus free shipping at B&H Photo. This ties a price we found on Amazon, but there was only 1 left when we posted this, otherwise this is the lowest price we found by $19. This dock works with iPhones and iPods that have the 30-pin connector, but has an AUX input for attaching other audio devices. The speaker can also run on AAA batteries if you want to go portable. There is no sales tax (except in NY).
