Mini Dock Plus, or Mini Dock Plus for Mobile Workstations?

Putting together shopping cart, noticed that Lenovo offers a "ThinkPad Mini Dock Plus Series 3" (433810U) and a "ThinkPad Mini Dock Plus Series 3 for Mobile Workstations" (433820U).

433810U only mentions that it works with T400S. 433820U mentions T400s, T410, T410s, T510 and W510, and states that the power supply is optimized for the W510. Aside from the power suply the specs look the same. When I'm on the product page for the T410 the accessories screen options do not include the newer dock (433820U).

If I want to do dual external monitors can I used the older Plus dock, or do I need to buy the newer Plus dock? There's a $50 price difference between the two and I don't want to spend more on a newer dock if there's no reason to.

Thanks!

FYI talked with Lenovo support and got the answer to my question: The Mini Dock Plus for Mobile Workstations is intended for the T510 because of the power requirements. The "regular" Mini Dock Plus works fine with the T410.
