Jim - thanks here in public for your quick replies and for e-mailing the details and the pictures of the ROPS - glad to hear you have conducted highly complicated scientific testing on it /w3tcompact/icons/grin.gif. I sent them along to the guy who needs one. As it turns out, he went ahead and ordered a new one, because he's building a house and didn't want anymore projects. None of us, I am sure, can relate to that!
