I have the one you show in your post. Very high quality with filled gauges. Used it 2 times and would consider selling. You can email me at nomobux AT fairpoint DOT net Change the ones in CAPS to you know what and I can send pics / discuss. I also have micro bore hoses for same.
I think you are giving them too much info. As I read it, you almost perceive some of the problems being the LCD or yours. Kinda of opening the door for disappointment.
Option. Surprised the new ones don't have it. Well worth the price. Don't get the one from the guy in Brazil. Get it direct from AGN Technology @ $128 shipped.
