My main torque wrench is a 3/8 Snap-On clicker that has served me well for almost 20 years. IIRC they're about $150 give or take and well worth it to have in the tool box, especially as you learn more and build your wrenching confidence. The biggest thing to remember about torque wrenches is to not drop them, as you'll need to send out for recalibration.

I've also got a 1" drive Caterpillar-brand that's about 4 feet long and good for a few hundred pounds of torque, but that's probably a lil' overkill.
