A good crimper
If you have a vice, there is a very good way to make yourself a good crimper with practically no cost. Take a nut, smaller than the lug, and split it in half. Then just stick the cable in the lug, put the nut around the lug and stick that puppy in a vise and crank her down. On small stuff, you can do the exact same thing and use a pair of vice grips in place of the vice. Some of us are pretty cheeeeep and look for other ways than having to have it done, or buying some expensive tools, that will more than likely get unsed only once or twice before being borrowed, lost or rusted up.
