Refiguring versus buying new?

Okay here's my dilemma: Buy a Coulter 13.1" and have an Optical genius like Steve Swayze refigure it to his standards of perfection for a little more than half the price of a new mirror figured by the afformentioned optician.
True the all-new mirror will be based on pyrex, but as far as final PTV and smoothness...is there an appreciable (subjective) or testable (objective) difference between the two finished surfaces?
Maybe that's an obvious "NO" but if it is, I don't know that as I'm still quite a novice and certainly have no experience with having mirrors refigured and resurfaced.

There is no difference final figure-wise between making new and starting from scratch. If you start from scratch, the figure of the mirror immediately after polishing it out is almost always far worse than the worst already finished mirror. The final figure is all that matters.
