I'm actually in the process of starting a side business specializing in garagedoors. my dad did that when I was growing up and I just leanred from him. I bet I've installed and repaired over 400 doors at least. if I was closer Stan I woulda come and helped. sounds like you had a tech there in less time than a flight for me
