Seconded on the Thermapen. Mine is now a "classic." My mother-in-law bought it for me with a hideous Guy Fieri flame job on it; fortunately I was able to get a free glow-in-the-dark silicone sleeve.
It's also worth pointing out that decent pans and decent knives last forever. I have some good Costco pans and some basic Wusthof knives that are sixteen years old and nowhere near done.
