So it took hot flaming oil to assess Rich's worth! My personal respect and gratitude goes out to Rich because he does his own empirical evaluations and tests, something that many of us either do not bother to do or do not have the bandwidth to do because we are busy "pushing" equipment out the door.
Thank you Rich.
