Aftermarket TPMS
Search function is not working for me today.
Can anyone recommend a good TPMS, preferably that can work with two sets of wheels without swapping, or is very easily transferred?

I've seen some gadget in Grassroots, in which the valve caps monitor the pressure and send a signal to a dash unit that gives you a readout. Is that thing for real?

This is what people are using now http://www.stackltd.com/tpms.html. I believe it's around $2,500.

Hmm, don't want it that bad. Just wanted it for time trials to see when tires are up to temp as I'm moving to slicks from DOT's. I will get a feel for it, but thought it would make the transition easier to be able to see when I can step on it. Will be a challenge to make the slicks work.

Tread temp and tire temp resulting in a pressure rise are different.
The former builds much quicker than the latter. You will gather a feel for it, but there are very specific techniques to build usable (as opposed to topical (or tread)) temp, quickly.
Just not sure you would see what you're looking for on a TPMS unless you get an even higher end unit than the Stack "Lite" version (the $2800 unit) or, better yet, I would recommend the use of IR sensors for the tread temp.
Believe me, the delta in the coefficient of friction between a slick NOT YET to operating temp versus one AT OR NEAR operating temp, it's much more obvious when that happens on slicks than on R-comps...
