Cam grinder/manufacturer opinions

I've read a lot of talk about cam grinders, etc. My question is who do you trust most when it comes to camshaft recommendations?

Comp Cams? Oregon Cams? Lunati...?

Just curious as to your opinions and experiences.

I agree on Oregon Cam Grinders.
I told them the intended usage and what I thought would be what I wanted.
They agreed, ground it for me, and it was here within a week for under 200 shipped.
(I wanted a cam with good torque plus a little hint of lope to it)
