ignition Controller

Okay im ready to look for one and need to know a good place to order (that is cheap). Im thinking of getting either the MSD SCI, or the MSD 6A. which would u suggest? Im also prolly gonna order a new MSD dizzy cap and an external MSD coil.

either msd or crane. if your going with turbo later then i believe that the crane model either has or has the abilty to have an optional boost retard w/ in car dial.
