made2dock makes some pretty good docks for the iPhone 4/S called dock-IN-case. There are these two models (Original and Slant) and a desk model that fits neatly in the cable hole in your desk. All models are heavy and well made. The Original is a bit heavier making it easier to pull out of the dock with one hand.
What really sets this dock apart are the sizing options to fit many different sized cases and bumpers.
