Timing Lights with advance any good?

Have you check to see if you can get parts for the light? I had 25, or so year old Snap-on that I picked up at a swap meet and the external wiring was bad. I hunted around on Ebay, Craigs list and Google and finally found the cables. I don't remember where I got them, or exactly what I paid fror them but it was less than 20 bucks because I wasn't going to throw a bunch of money at it. I still have the light and keep it as a backup in the race car trailer, and we drag it out and check it against on we know is good.
