What brand of Tire Pressure Monitoring System recommended?

After researching several systems, I felt more comfortable with tst system. I put senders on all MH tires, the tow dolly and on the toad. 10 senders total. Cost was about 500.00, the cost of a replacement tire for the MH. I still check all tires frequently with gauge, as you should. I do however feel better going down the road with them in case of road hazzards.
