Spencer's interpersonal skills are just fine in my books. If I had any interest in a Transformers pin I would deal with him in a heartbeat. His price is great, the machine is great and he's been around long enough to have a solid reputation in the pinball community. He's the kind of seller that I know I could trust his word on a machines condition, even without seeing it in person or pics.
I understand that he must come across as hostile, but you probably are unaware of how many tire-kickers and time-wasters there are in this hobby. If you're selling a machine, prepare to waste a lot of time replying to people who will ask tons of questions and then, without explanation, never get back to you (leaving you hanging and possibly missing real sales). If you've ever posted an ad on Kijiji, it's probably worse than what you get there.
So, number one rule: nobody wants to deal with an asshole. Be polite, be nice, be brief,ask the questions you have, and let the seller know if you're going to buy or not. Don't air your dirty laundry out in public, because the people who have been around here longer than you will almost always be favoured by the rest of us, simply because we know them. Spencer wasn't being rude, he was just pointing out that you are probably a tire kicker. I would make the same assumption. Most of us probably would. I get that you're looking for the best deal you can get on a great pin that you'll love, the first pin is a big deal and is a lot of money to plunk down, but understand that you're new to this and don't know what it's like from anyone who's been around a while's end.
Don't be offended, stick around, the canadian pin community needs more enthusiasts.
