Don, as much as I appreciate what I think the sentiment is, I don't understand the guy's post either. But, since you've chosen not to delete the thread, I'll go out on a limb and guess that you get some form of gratification out of this, so I'll reply.
First, your hair-splitting is for naught. I would rather a PM member have the mill than a non-PM member, whether he or she is a collector who only posts pictures of it in an attempt to impress others through mere custodianship or a true aficionado who wears it out for the pure mechanical and tactile joy. As tenuous as it is, thanks to you I have a membership in a group of like-minded people and I was serving the good of the group by making the mill's availability known to them.
Second, it ain't an auction so your hypothetical hand-wringer doesn't wash. It's fixed price. I didn't run up the price by calling attention to the fact it is for sale as I might have if it were an auction.
Using your own hypothetical, imagine if you will a member of PM, a dedicated practitioner of the machinist arts, who had wanted a Sixis 102 for years and years and searched for one tirelessly. Just before Memorial Day Weekend, one came up on eBay while he was busy getting ready for the big annual family gathering. He just had time to check into PM, but not to check all of his other usual sites and some Wall Street leveraged buyout take-over suit with a passing fancy for pretty things mechanical picks it up on a whim and never uncrates it. Of course after the fact some members here were delighted to point out to our guy that he blew his one chance to get one. Inconsolable, he chained his Brown & Sharp universal dividing head with the complete and highly polished set of plates to his ankles and jumped off the family pontoon boat.
And it should be "Imagine for a moment you are someone WHO has done their due diligence . . ' People are "who"; things are "that" - a subtle but significant distinction.
