List of Good Zigbee Repeaters

Hey guys,
I just received one of these Zigbee On/Off Controllers which I'm wanting to utilise as a "repeater" so I'll be interested to see what it does when it's inserted into my Zigbee mesh.
First impression (I'm currently at work) is that it's quite small at 80x40x20mm and that I should be able to modify it to provide an isolated contact. see images below where I'd cut tracks "Red X" and make a single join "Green line".
Not that I'm going to do that with this one...but I have other plans..... he he he

Nice little cable clamps which are push to release.
