Which device can I use to build a Mesh Network with Zigbee protocol

I am actually planning to build a mesh network and test the self healing of the ZigBee protocol. Please suggest me the suitable and cheap hardware devices available in Digi that I can use to do the work.

Aravind,

Generally this is something you would talk to Sales about. But I would suggest XK3-Z8S-WZM
