I think I'm going to get one of these: http://www.vernier.com/probes/temperature.html (the Go!Temp)
Try to look past the fact that it seems to be marketed toward middle school science classes.
My last thermometer was the probe thermometer from target but mine mysteriously pooped out on me and I'm not the only one who has had problems with it. I was willing to give it another try, but I've also wanted to look into something that could be used for data logging. I could use this to monitor my mash tun temp, sparge water temp, or fermentation temps. It includes more data on accuracy and resolution than most storebought standalone thermometers and I think it will hold up to being submerged better. It is also very clear about its range (-20 to 110 C) and that will be perfect.
