If you have a basic understanding of how engine electronics work, you can easily learn how MS works with simply reading their manuals. I believe they also have a book out there with lots of basic information.
If you don't know anything about efi and don't want to learn, I suggest getting a Fi-Tech or the holley equivalent. I've heard good things about them, and should give you the same cool features of the port efi MS can offer.
It is pretty cool to sit in my car on a 50 degree day and hit the key without touching the accelerator pedal and it starts right up.
