madvapes has a couple sweet PTs, a black delrin one and a light blue clear-ish one. You can also make one for next to nothing.... or you can go buy a corncob pipe, put an orange LED in the bowl head, and have a corn cob pass through! I use it all the time, since I spend most of my day in my truck. The only thing to keep in mind is if your going to use a PT in your vehicle, you need a USB adapter that has an output of 2A or better. Most of the cheap ones are only 500mA.
