Best Timing Light?

Reason I am asking,is the the B & M supercharger recipient.

yea..i want everything perfect before it goes on. it was running great, something somehow got outa wack.

so, i will degree the cam, i will find out exactly what curve my distributor has because that is unknown to me, and i need to check and see if the power valves in my carb is blown because the engine backfired a few times...

i will follow that timing/carb thread with all the information that 67dart273 put in it regarding degreeing the harmonic dampener, and proper timing, so i was looking for a good timing light...lol
