Are you looking for one that interfaces with a cell phone or tablet? Most of the systems have their own monitors and use radio frequencies. There are several: Tire Minder, TST, some others that don't immediately come to mind.
I have the TST TPMS: Tire Pressure Monitoring System. Other posters may chime in with their particular preference in TPMS's. Most now attach to the valve stems rather than inside the tire itself. Since you're getting new tires, and looking at a TPMS, now would be a good time to install all metal valve stems for the TPMS sensors.
