TPMS for Bag Pressure Monitoring

[damnyankee36]

Has anybody ever tried using an aftermarket TPMS to monitor their bag pressures? I want to get rid of the old mechanical gauges but I'm having a hard time swallowing the cost of typical digital systems. I don't need the auto level functions, just a decent compact digital readout.

I'm just not too sure how accurate these systems are. Even the system on my late model car is a little flaky, it seems.

Here's one I'm looking at. The senders screw on the tire valves. I could use a common NPT to schrader adapter. It only monitors 4 pressures so I need to figure out what I want to do with the tank pressure. It also measures up to 99 PSI.
