I would only do 3/8 and 1/2 unless you're getting into little engine stuff. Typically you can find a 3/8 with a wide enough spread to do things even like valve covers. I've been wrenching for 15 years now and only just now bought a 1/4 to do rocker shafts.
I'd also recommend a digital one like the one in the below link as it can back-check torque on your wrenches and also serve as a stand in for when your torque wrench doesn't quite fit the application.
