I'm just going to say I don't agree with some of the narrative that the Heighway system and hardware is cheap junk. If they had a working support system, and spare parts available, I think no one would really have anything bad to say about it, compared to the major pinball companies.
The engineers that put all this together should get full credit for their success. Working through tough conditions, no less.
My Full Throttle has run without a dark day since the day it first arrived for me in 2015. And from what I've seen online of support issues, some spare parts would solve any of the problems people have.
I know the piling on is going on and there are a lot of burned people, but just wanted to offer that up.
