MSD 8680 question

I had to crank a while before it would start. Then after a few month's it died . I sent it back for a free repair but when I hit my key with the stock ignition it fires up instantly. I don't feel like getting stranded again. It's easy to keep a spare of stock parts. I could rewire and have my stock ignition for a back up but car runs great with the stock setup with Blaster 2 coil.
