Thank You, yes that helps a lot.
The pricing was on Amazon and general google searches, I was seeing starting prices ranging from 899.99 to just around $1000. I'm ok with the idea of using 2 controllers in the short term. I'm spending 5K on additional lights so if I can save money on the controller, that will help a lot.
As far as the transmitter and receivers go. There is no manual pairing mode, they sync automatically. I originally purchased 1 transmitter and 2 receivers but then brought another set a year later. I only needed the additional 2 receivers and when I turned them on, they automatically paired with the original transmitter. So if I had 2 going at the same time, I think I would get a lot of problems. I think I will need to upgrade my wireless system too.
Thanks again for the help.
