I have to tell you that in my experience with jfesler, he's a great guy. I don't know why what he said hit a nerve with you, but although you're entitled to your feelings about it, you're dead wrong in your response to his post. This is all drama about nothing. He simply made an observation that you have a shit ton of machines (you do), and trying a piece of glass out for $300 or less would be money well spent. Perhaps the way he worded it offended you...but it was cancelled out by the rest of his post (which you skilfully edited out) which was informative and helpful in answering your question.
I'm thinking you might need to take a deep breath here and maybe PM the guy an apology. He's been very helpful to me and many others on this forum.
