I know a few years ago I offered to help some people with issues they were having with their pins, and as you say LTG people don't seem to appreciate being helped out. I wasn't even charging for my time, just parts, I was doing it for the love of pinball. Or maybe it's not they don't appreciate the help but they expected me to be at their beck and call like a real tech (I remember one lady called me at my real job when some parts came in and demanded I leave my job and come over to install the parts right that instant...) In the end I decided I didn't need the headaches, it just wasn't fun for me.
