Here's a little know fact about the PR03X. It supports 4 displays. You can plug 3 into the port replicator (1 15 pin analog, 1 DVI and one display port) and leave your laptop LCD open as a third display.
The last consideration is the AC adapter (if any) that you want. You can use the one that came with your laptop. If you only take your laptop with you occasionally that is the best bet, nothing else to buy. If you are on the road with your laptop frequently buying an AC adapter is worthwhile. The easiest way to pick the right AC adapter is to look at the onethat came with your laptop. Generally, the bigger the laptop display, the more powerful AC adater you will want.
