I'd have to question what "coming into their own" would mean in regard to SI-TEX.
They are oh-for-2 with 2 of my friends. They DO NOT include wiring diagrams with color codes for installation. Had to call tech support with pencil and paper in hand.
When the LCD screen crapped and went black, it took almost 5 weeks to get it back although after 3 weeks he was told "it's going out tomorrow" a half dozen times.
I've said it before: "They ain't your father's SI-TEX anymore!".
BTW- One of the guys is a retired charter captain that learned on SI-TEX paper machines and was a fan of theirs.
