I was wondering... do any of you have a contact (like the name of a real person, not Support@CenturyFlight.com!) ) at Century Flight Systems in Mineral Wells, TX? The reason is simple. I have an NSD1000 HSI and it is terrific - until it isn't. Had to send one in for a repair. Estimate was ~$3K. Ended up significantly higher, but the real injustice was the 90 day warranty. Seems to me if you put that much work and that many new parts into a unit, you might be a little more confident in your work and warranty it for, say, a year. The repair cost about 33% of a new unit. So, I've written 5 emails to various people and titles who I thought *might* care, but not one of them has deigned to reply. That is why I am looking for the name of an actual human being there - president and CEO included. I am in a similar-but-not-related business in terms of the cost of our systems, federal government oversight, regulation, liability, etc., and we wouldn't consider treating a customer so poorly both in terms of the warranty issue and the simple common courtesy of a response. Even a polite "go pound sand" would have struck a better chord...
