Great thread. I'm definitely going to have to check out the thremapen.
As far as the big hard-mounted thermometers go, the one I've been using has been pretty good. Its the ~2" model made by Fermentap and I have it mounted to my mash tun. Checked it against every other thermometer I have a while back (checking them all against each other) and it did as good as my digital ones.
The only knock I have against it is that it sometimes hangs up inside. I've gotten into the habit if giving it a tap with a knuckle on the glass before I read it. Sometimes it jumps a few degrees. The temp it jumps to is accurate but the need to tap it first is a little disconcerting.
