Oh, I"m not looking to replace my current home's CZ II system. It works great. I am deciding what to put in a new home that we are constructing now - either CZ II or Infinity. I'm familiar with CZ II so would be happy with that. But, the Infinity system and zoning looks even better. It does cost more - and I have yet to see the cost differential. But, I'm definitely leaning that way.
I may contact you offline. Thanks. I have a limited selected of contractors to select from that my builder is willing to use. I'm kind of at their mercy. The one I'm working with now seems pretty good though - we'll see.
