ThinkPad Port Replicator II

IBM ThinkPad Port Replicator II The Port Replicator II (Model # 74P6733) is the cheapest dock IBM sells. It contains basic pass-through connections for notebook ports, including power pass-through. It comes without integrated power supply but provides the same AC port as found in a ThinkPad, so you need to use either your Thinkpad AC adapter or another IBM AC adapter. Besides all the pass-through ports the Port Replicator II comes with an On/Off switch and a slot for a cable lock (only for the dock though).
