Msd 7al-2
I'll second the opinion on the Mallory Box.
This one:

It has a ton more features than the 6AL. Very user friendly. Quieter than the MSD Digital 6. No pills or tiny dials.
One of the best things about it is the fact that it comes with connectors right at the box. If you ever have to pull it out, you don't have to rewire the whole thing.
I've had MSDs in the past and never had any problems, but the feature list and price point on the Mallory has got me using their ignition on all of my recent projects.
