Does anyone have recommendations on the brand of new distributor who may provide the "best" quality, or have you had great experience with one (or bad experience with any of these)? I am comparing Spectra, Cardone, WPS, and Autoline. All seem to be reasonable price except for Autoline but I am willing to shell out the extra few bucks to not have to monkey with the distributor again if Autoline is the "best".

Looks like Rockauto has these brands of new distributors to choose from:

I'd go with the Cardone. Lifetime warranty, and I've had good luck with their stuff.

Keep in mind, they're ALL knockoffs of the original Hitachi unit.
