It's so common around here to see independent controllers and equipment installed by the majors. Shows a smart customer specing what they want. I just seen a 4 bank the other day of galaxy 4 controllers with HW machines that modded otis 311 controllers/machines that was done by TK. Even Otis knows they can't beat maxton and uses their valves. It's a nice change they're to see a little less proprietary stuff trying to lock in customers
