Thanks everyone for the replies. I never understood exactly where the MSD box went into the ignition setup. I thought maybe it replaced the coil, but it looks like you use everything you would normally use, and then add the MSD to get the benefits of multiple sparks at low speeds.

I agree that hiding that big red box would be an issue, and since we rarely get below 45 degrees here I won't have to worry about the cold start thing. I think I'll pass for now, and maybe just put one on the drag car I'm planning some day.
