Why embarrass yourself by making this a personal fight? You've totally lost the premise of said posting, a high concentration of call outs, which incidentally, we don't if this problem wasn't addressed already. Secondarily, any system upgrade will be determined by the size of the system, one or two rooms versus several buildings, which scenario is feasible to upgraded on a regular basis at an reasonable cost? So as you've repeated, my one upgrade at $27,000 seems reasonable if system last for the next 20 years.
