I have a degree in physics from UCLA. I know the science world and believe me NO ONE takes anyone at their word in science. It is just not done and just not good enough. And these guys aren't "geeks". They're full Ph.Ds and often times come up with contrary - opposite findings.
All the more reason for an artist to trust his eyes and not someone else's.
Which is why the OP prolly ought to rent whatever rig he's thinking of buying first (which I'd say is some of the most often repeated advice on this forum) to see if, in his eyes, it's worth the extra dough.
