I just thought of another thing their pixels are going to be more expensive because they have 4 lights in each. Red Green Blue (this forms the RGB of any colour) and a 4th of Warm white. Majority of pixel nodes don't include the warm white so I don't know which type they are using. I emailed them back but guy is out of the office until next week.
Here is their outline for the 2200 quote I apologize for large pictures.
Here is my ideal outline and pixel counts that I want to run when fully operational. Again these lights with windows would only be for Christmas maybe Halloween where as roof line I want to run permanently. I will have more stand alone displays in the yard as well that aren't included.
