Need advice on buying DigiMesh Development Kit

Hi there.

I have been working on Coordinator<-->Router<-->End Device configuration using Xbee Pro, but couldnt get it to work so i am planning to buy a DigiMesh Development kit , i was wondering if this Kit can perform the task of sending and receiving data from Coordinator <--> Router <--> End Device?

here is the Kit i am talking about

Waiting for suggestions...

So you think throwing some more hardware at the problem will be the solution. I don't.

Which XBees do you have now? Series 1 or Series 2/2.5?
What are they attached to?
What problems are you having?

Yes i can buy some more hardware as this is University stuff and i am not the only one to use that pair of hardware, if i change the firmware to DigiMesh, the other team working on it needs to change it back to 802.15.4 everytime they want to do some experiments.

Currently i have Series 1, connected to Mini USB Explorer.

My main concern is to Transfer Data from Coordinator to End Point using Router.
