Quoted from robertmee:
I would disagree....when I was searching for a Mystery Castle, I would PM a few of the regular pinsiders here that I knew had one, to see if A) they were interested in selling, B) if not, then keep me in mind in the future, and C) keep on the lookout for one, since owners seem to travel in packs. I was always courteous, apologized for intrusion, and thanked them for their time. And in the end, it worked as I both met several enthusiastic MC owners and met a Pinsider who decided to sell me theirs. This is a forum of like minded enthusiasts...I welcome anyone to PM anytime. I don't find it rude at all.
I agree Robert, I do this all of the time. It's all in the way you present it. I'm never rude about it and it has turned out that some people are actually interested in selling or will contact me about one they come across. I've really never offered a price in an initial contact and usually just ask if they would consider selling a pin. If they say they are not interested, I leave it at that; if it's something I really want, I certainly understand why they want to keep it. I've never had a rude reply from any of my contacts and most people are really super nice when you ask. I've even had a few people contact me about my Fathom; it's not for sale, but it's sort of cool knowing you own something someone else is looking for and I'm always happy to talk shop about a machine(s) and wish them luck in their hunt. Again, I think if you are kind and your initial PM/email is presented in a non-aggressive manner, it's perfectly fine to ask.
To get back on the subject, I think crazy money can buy about anything. Maybe not at the present, but putting up a big offer can get stuck in someone's head and stay with them until they are comfortable selling. As my grandfather once said when someone asked if one of his favorite trucks was for sale when they came to actually came to look at another one that was, "Everything's for sale if you've got enough money."
