If you can afford the one that stores the temps it would be extremely helpful and make things easier if you're doing it all yourself. If you have someone to help, any pyro will work, even an infrared one, although the probe type will yield the most accurate results. Sounds like you're starting out on the right path, tire temps are the key to setting up your car properly. Good luck!

I use a "Joe's" pyrometer. It's a handy shape and the needle tip lets you stick it into the rubber instead of getting just the surface temp.
To get good temps requires someone to write them down for you if it doesn't record. Same with pressure though. I can go around the car and record pressures, then go around a 2nd time and they're all lower. I don't like the IR ones. It seems to take too long to register and the temps can fluctuate quite a bit.

I have the economy model I think around $100.00. It has a hold feature that I don't remember how to use. As far as I know it will not hold 12 different temps. I just use the pencil and paper method. I have had good luck with Longacre stuff in general. My

get the longacre recording unit with stopwatch. it forces you to get the temps in order, records them and beeps when the reading is stable. as for the stopwatch, it is one less thing to carry for whoever does your laptiming and tire temps.
another trick is to put tape on the back of the pressure gauge and write down the pressures as you take the temps. when back in pits move tape to session sheet.

I had the probe non memory type and sold it for the unit with the memory because it was a pain in the ass to write everything down(when i am alone). its so much easier for me to use. my unit will store 10 sessions of all 12 readings, so comparing is easy also. look on http://www.racingjunk.com or on ebay for a used one. they come up all the time. i think i paid $150 or $175 for mine.
