I'm the first to admit that I'm not exactly easy on probes. I leave them in the 400F oven for long periods of time to check on the progress of a roast, leave them in the grill (shielded by the meat, but still) for a minute at a time, and make frequent use (roasts, fish, candy, what have you). Still, I haven't found one that didn't suck.
Gadget lover that I am, I asked my chemist wife to recommend a brand. Now I have recently ordered an Omega HH503 with thermocouple. The base unit is dust and splash resistant and armored in rubber to protect against falls. The probe can measure from -450 to 2500F, though the plastic parts can only tolerate 220C/420F.
Complete and total overkill, but I'm hoping for much greater durability for my $100. I will let you all know how it turns out, but in the meantime, is anyone really happy with a probe thermometer?
