I have an existing RRA2 system, and I'm debating whether to get a Grafik Eye QS in my home theater (5 zones) vs hidden dimmers and a keypad. The electrician we're using is charging several hundred more to install the Grafik Eye QS vs dimmers. Does that sound right? I will be doing the programming myself. Also, if I'm programming myself, I'm assuming there should not be any additional charge from the electrician to install RRA2 dimmers vs regular dimmers? This is a new unfinished part of the home, so not retrofit.
