Which T43p docking station FRU comes with power supply?

[alins]

Looking at
http://www-307.ibm.com/pc/support/site. ... NXNTP.html

Am I correct to assume that

- Port Replicator II, FRU 13R0292 (which replaces 74P6735) does not come with a power supply?

- Thinkpad Dock II (FRU 2877-10U) comes with a power supply and cord?

- Thinkpad MiniDock (FRU 2878-10U) comes with a power supply and cord?

I am trying to see which one to order from CompuVest.com.

Have there been any technical changes to these units? For example is 13R0292 "better" than what it replaces (74P6735) in any way?

Thanks!

To my knowledge only the Dock and Mini Dock come with their power supply.
Port replicator is not a docking station even though looks almost identical next to the mini dock.
