there appears to be heaps of brands on the market - powerspak, accuspark, ultraspark, 123.
the first 2 weigh in at about $60 on ebay
all seem to be the same desing - basically a sensor on a flat plate, replacing the standard points.
is there any difference between them?
also, the picture are confusing - they have two leads coming out , whereas i only have one wire going back to the coil
