Yeah, I hear ya about the confusion with the devices!! I can see where the probe device may be the most accurate for ambient temps, I just dont like the fact it only reflects the level the probe is on. However, I do use a digital probe thermometer in my brumation room is a general temp indicator. The infrared gun is geared towards reading the temps off of surfaces, like engine blocks. IMO, I dont think its really designed to read ambient air temps. I quess if worse comes to worse you can always hang an old fashion mercury yard thermometer in the room to get a general idea what ambient temps are. A good friend of mine that maintains a large collection told me he relies on the digital probe thermometers the most. According to him, they are cheap and reliable, and some models can give you the min and max temps in the room so you can see the fluctuations that occur.
