You have to ask yourself what you want it for. If you want it to be a racer Yes if you want to turbo or supercharge and need the better spark Yes. You have to pay for what you want it for. Id be happy with just an n12 pulsar dizzy because its cheap to begin with and how often is it going to break and if it does stuff finding parts for it just buy another one and modify it. I wish we got electronic dizzys over here. It would make my decision about which one to use much easier.
