I tend to shy away from this electronic stuff that seems to be the cause of all sorts of issues.
I also avoid the "electronic" stuff. I occasionally might buy something if it is so cheap that after a failure, I can put a postwar e-unit in it and still feel okay. (this weekend $40 for a boxed dual motored MTH diesel that so far runs fine conventionally)
I think without the "electronic" stuff this forum would lose 50% of the threads.
However, they are impressive when they run properly.
