Well, I thought I had done my due diligence by checking on QRZ.com and Google maps but the most obvious search - on Google - I seemed to have passed over and it has cost me $450 to a scam. I listed my desire for a Flex 1500 on a Canadian swap shop website and a few days later got an offer of one for $US 450 from someone claiming to be Daniel T. Smart and showing the call WD0EMN. The rest is history. Clearly I've learned my lesson - the hard way !! I have documented all my correspondence and will happily include my experience with those of any others trying to pursue this.
