quick mopar distributer question

So what should i do guys? should i bu the limiter kit and install it? should i send my distributer to don? or should i just buy a new distributer that has an adjustable mechanical advance built into it? i can get the new mopar distributer that has the mallory guts inside it for 185 or i could buy a distributer from don at fbo for around 180 as well and i'm sure the distributers he has have the adjustable mechanical advance as well.
