Anyone using a tire pressure monitoring system? Impressions?

[DSK M3/4]

looks like there is a system that installs a sensor in each rim and then transmits data to a little display that plugs in the cigarette lighter. i think it's around $220. anyone use it?

I am thinking of getting it and am going to talk to someone about it over the next couple of days. The part I am a little curious about it that it beeps after a 10% or so change in tire pressure. I know for a fact that when it is cold out and I run hard or long I change about 3-4 pounds which might set off the sensor?? I'll let you know this guys experiance.

yah i've seen the thing it wraps around the rim of your tire ?? Was looking at buying one but can't find someone that already has.....so one of y'all hurry up an buy it damnit

Actually I think there is two different systems one that wraps all the way around the inside of the rim which is the old one and they made a new one but I forgot. The new one is suppose to be more senstive.
