I would recomend the rex's speed shop cdi's they are good quality and look almost like the original.
I got the pulserless cdi for my dt360a.

This could be a alternative to the jaycar cdi.

Ouch, not too pretty in there ::). I love PVL ignition and have it on three or four bikes but reckon you'd have been happier with a heavier flywheel ignition on the 500. I'm using DT400 CDI with a Rex's Speed Shop black box on my 360 which will be used for dirt track. Time will tell and at least your bike will start easier ;).

Dave,
Get all of that surface rust off with some wd40 and 1000 grade wire wool. It won't look so bad then. Looks like she's had a guts full of water.
