Yes...with over 200 transactions of my own..I have had my share of Savoir Faire! The most recent was a guy who emailed me to buy my phono stage with his offer that " I will buy it! I am serious and will not back out of the deal..You can count on me"...when I read that nonsense..I know whats coming next...and of course it did 5 mins later. But instead of telling me that he couldn't afford it, or his wife said NO..he tells me that he actually already had the same pre amp and just wanted to see what my best price would be, so that he would know what to ask when he sold his!!UNBELIEVABLE!!
