$20? well, i just went there and the cheapest one they had was for $30. if that's the case, then is there somewhere else that you would recommend looking for timing lights?

i'm going to look at this one ...

it's not the cheapest one i found, but ive never heard of the company that makes the light Autozone had for $29. Advance Auto was selling the same thing for $37!



anyway here's a link Craftsman Timing Light

It's not so much of what kinda of timing light to use, but learning to identify the marks and learning how to make adjustments according to all kinds of ignition set-ups..
