I was about to pull the trigger to purchase 20 dimmers and a few keypads for a RadioRA 2 system when I saw discounthomeautomation.com has Vizia RF+ VRMX1-1LZ dimmers for $43. This would cut the cost in half assuming it works. I'm skeptical as I keep reading posts about Z-Wave range issues, turn on/off delay issues, and the integration of scenes with the OmniPro controller. Status updates on the keypads is important to me as the ability to call a scene from the OmniPro. Obviously I would rather spend the money on RadioRA 2 if Z-Wave is going to be problematic.
