TPMS saved the day two years back. My wife hit some road debris at 65 mph, and within the minute the light came on. She got the van (our Sienna) off the road before the tire was flat. It was quite a big slice, and the tire wasn't saveable. But thanks to the warning, she had the 10 seconds or so required to act. At minimum we saved damage to a rim, quite possibly the van had she lost control, and maybe her and our daughter's life.
It's no different than air bags, ABS & stability control, AWD, etc. If you are a Luddite and don't believe that any of this might just save your life, well, go find something from the 70's and enjoy.
The OP didn't ask your opinion on whether he should ditch or defeat the system. He simply asked how to add additional sensors in an easy to live with and cost effective manner. If you cannot help the man with useful information, back off and leave him alone.
For the Toyota Sienna I bought 4 new TRW (Toyota OEM) sensors off of e-bay for under $100. They are not programmable, and each has a unique ESN. I bought the ATEQ Quickset Tool (yes, another $150), but now I can easily reprogram thru the OBD port at will in my own garage when I swap tire sets. Subaru is listed in their Apps page.
