Ignition systems.....Which way to go?

[sam's 72]

I want to get a complete Ignition for my truck. The 383 will be in the truck in about a month. I want to go on ahead and set up a good ignition in it now for the 383 thats comming.
I am stuck between a MSD, Mallory or http://www.davessmallbodyheis.com/

So as usuial I am turning to you guys to help me out. I want the electronic, but I don't want to go with one that has the coil in the cap. I been looking hard at Dave's HEI due to the fact that you can get parts at your local parts house. But If I were to go with MSD or Mallory. Which one is the best? If I go with one of these I will go with a billet distrubtor.
Also lets say I go with MSD what all do I need to purchase to get it going in my truck? Please give me a detailed parts list.
I know I will need the distrubator, and external coil, is there any thing else that I might need?
This engine will see 6000 RPMS at times, and is going to be putting out 450 to 470 HP.
Thanks,
