As a few of you know I'm in the process of upgrading our home alarm system and I think I'll start with the bell box. Is the ADE Reson8 a good replacement for a 21 year old Risco Novagard 4 alarm. I know that the bell box electronics aren't protected very well so I would make some sort of cover for the circuit board to protect it from the weather. But overall is it a good bell box or should I go with Ventcroft? (I'm trying to do this as cheaply as possible)
