+1 to this. I used my digital thermometer last weekend for my first all-grain, but I was careful not to let the end of the probe where the wire attaches get wet. I will be using Bobby's write up to waterproof it so I don't have to worry about it next time.

So I got some bigger paint straining bags for my grain, got some bigger pots, increased my mash ration to 1.75 qts/lb, and got the weldless brewmometer from blichmann, and now I can control my mash temperature like a champ.

At first I used floating thermometers with my thick mash, but they seemed inaccurate and slow...but the main problem was the mash being too thick and the grains being too crowded. I then used to use one of those digital thermometers with the teflon cable and the probe, but apparently you aren't supposed to get the connection wet, which made my thermometer go haywire and then break. Now it's back to the trusty floating thermometer in one pot and the blichmann in the other one. The floating thermometers work well as long as your mash isn't too thick and you give it a bit of stirring every 15 min or so as C-Rider said.

I also recently bought one more thermometer ( Amazon.com: Traceable Long-Stem Thermometer: Industrial & Scientific ) and used a drill with a step bit to make a small hole in the lid so I can monitor the temperature when mashing and when cooling the wort after the boil.
The long stem termometer sounds interesting. Followed the link, but it never says how LONG the probe is.

+1 to the floating thermometer posts. I also mash in a cooler with one.
