Don does his know stuff, so a curve or use the kit is probably a good way to go.

I don't see what good it is to buy another distributor, unless you buy an adjustable mp one, and then, you still need to know what you want to set it to, and how to check it with a dial back light.

The kits he sells are decent. I don't know about a 5 minute install, but it is fairly basic. Again, you have to know what you want to set it to.
