Torque Wrenches...

[F34R]

The other thing too that no one has mentioned is that consistency is more important then the actual torque value. Most things that have a torque spec (like head bolts) mostly have a spec so that they are tightened evenly. As long as all the bolts are the same torque, it isn't as important that they exactly the correct torque amount (within reason). 5 ft lbs likely would cause no noticeable difference in operation.

So as long as these cheapy wrenches are consistent and close to accurate, you should be fine. Especially for something like wheel bolts.

For engine work I use a A-beam, lug nuts etc the clucking one does me well.
