Marshalls and TJMaxx always seems to have a bunch of iPod accessories. After my old DLO TransDock (TJs) did't work with the 3G (but did with the original iPhone), I found a newer model TransDock at Marshalls for $30. Works like a charm. it says that it wasn't meant for the iPhone each time you put it in there, but that won't stop it from working. Highly recommended.
