Can the Airport Express base station be extended? I'm thinking of replacing my home router (an older D-Link box) with the latest gen Airport Express base station. 

I currently have an older Airport Express unit (like this) that I want to use in another part of the house to extend the network, but not sure if the latest Express units can be extended... 

Or do I need to get the Airport Extreme to function as the base?
Looks like the answer is Yes. 

From Apple Forums:


  The AirPort Express can only "extend" a wireless signal....using
  wireless only....from another AirPort Extreme, Time Capsule, or
  AirPort Express.
