I use an Equus digital like this one.
Yup, good tools are expensive, I think this one was $109. You can turn the light on and off, read the exact engine rpm, check the timing advance or retard, all without turning the distributor. If you'll be spending a lot of time around distributors and timing engines, invest in a better light. If all you'll use it for is a yearly tune up, then a regular Craftsman light will be enough.
