I bought the Sendstation PocketDock mainly due to the line-out and am fully satisfied with the product. The adapter is solid and the sound is great! I use the dock primarily with an external headphone amplifier and own cables, so I can be the quality of the accompanying stripping say anything, but they are likely to be the thickness & plugs according to Apple's level. The iPod interface is beautifully smooth, but the mini-USB port was initially just the opposite, but faded away after a few plug operations. Because that's the only criticism that strikes me and my Ipod paired with the dock and Lossless files to an A / B comparison with my CD player withstands gets the PocketDock me very satisfied 5 Stars. :)
