TireTraker TT-400C vs. TST 507RV

[JimOneil43]

Trying to do research on tire pressure/temp sensor systems and wondering what everyone has to say about these 2 different systems. Pros and cons of each? The TireTraker seems to be a little less expensive than the TST507RV.
Any experiences?

Take a look at this thread. It covers many of the systems. MSG #48 has my recommend.
