Tony,
I must say I think my favourite feature is the web monertering. I have been away over the hoildays and always had that small worry, did the power go out? I have been off and on thinking of a design for a heat back up (battery powered) to take over in a power failure...

The unit looks quite good I currently have Herpstat pros and an ND but I am planning on adding a pair of enclosures and well... It is a way off yet but I am just planning a head.
