Tire pressure monitoring systems

I am really leaning toward the TST system but I am not real crazy about the display. Seems they use the same system for all vehicles. Having only need to monitor 6 tires, the "extra" trailer on the screen is frankly a waste. I guess it would apply if I added a toad. I also don't like the fact it's sideways. Call me OCD but it seems like the display should align with the RV (IE forward) I like the fact that they are pass through sensors with replaceable batteries. The Tiretech is also on my list. It's considerably cheaper than the TST and I like the display much better. But it does not have pass through caps. Can I assume these systems are OK with valvle extensions? Don't care for the pressure pro monitor at all. I am sure it's a good system. Frankly I just want the best bang for my buck. I know most of you like to chime in about what's x dollars compared to a tire failure, etc etc? But more money does not always mean a better system. Surprisingly there is little in the way of reviews etc for any of these systems.
