Since the OEM Optispark is no longer available and my MSD has been plagued with an intermittent high speed miss since new I want to find out about the other options for replacement of this unit.

Has anyone tried the Summit #Sum-850060 for $199 or the Accel #59125 for $294 and what is your experience?

Arctic White '97 Camaro SS

I don't have experience with the Accel, but the $199 model price point indicates cheap components that others have had issues with. Fred may be able to chime in on the Accel.
