I am wanting to get a new optispark but don't know if I should go with the stock on or a aftermarket (I don't even know if there is a aftermarket one)
Where should I buy. If I go with a stock one how much do they run for, Thanks alot

 

Dynotech has their "dynaspark". It addresses lots of GM opti issues but has yet to be proven as it has only been out for a year or so. It costs $600. For that price you could buy 3 GM optis. Go with the GM unless you want to give the Dynaspark a try.

OEM opti is $200 from Jason Cromer or Dal. Use the search function to get their numbers.
