The one I like and use the most is a Wiha 28554 TorqueVario-S Handle, Newton Meter Scale 2.0- 8.0Nm not cheap but worth every penny, you also want to get these 2 adapters for a full range of uses Wiha 28582 Square Drive Adapter For 1/4-Inch Sockets and Wiha 28581 Bit Holder Adapter For 1/4-Inch Drive Bits.

That said I also have a Nm clicking Torque wrench and a beam type all work great and for even bigger stuff I have a larger 1/4 and 1/2 clickers.
