eXpansys offers the i.Sound Twin Charging Dock for Apple iPhone / iPod, model no. DGIPOD-1500, for $21.99. With free shipping, that's tied with our mention from last week and the lowest total price we could find, again by $4. This charging dock is compatible with any iPhone or iPod (excluding the iPod Shuffle) with a 30-pin dock connector. It also features custom LED mood lighting.

Note that this ships with an EU plug and a US adapter.
