If your exposure and development procedures are constant enough, you could even make a whole print without guessing. When my contact sheets are looking good, I know that I can print Tri-X at 14s G2.5 on MGIV for an 8x10.
Otherwise, test strip are easy and useful because you can assess how things would look when darker or lighter. Sometimes the "correct" exposure is not the one that suits the print best.
One thing that will be even more useful than a meter is learning by heart a sequence of time intervals that corresponds to 1/4 stop exposure. For example: 10,12,14,17,20,24,28,34,40 is two whole stops in 1/4 intervals. The difference in densities between 10 and 12 is the same as between 34 and 40, even though the first two are separated by 2s and the last two by 6s. Wonder why? Look at the shutter speeds dial on your camera.
