I hope you get the machine, it should be well worth the efforts to get in nice again. Scams doesn't happen very often, but delays and misunderstandings happens several times a year. One buy on ebay a decade ago was a scam, seller had loads of red marks which I should have noticed. Something when wrong, because seller had good feed back until the last few months before the account was closed. Another time I bought bee pollen from the UK and nothing ever appeared in my mail box. Seller was very angry when I contacted seller about it, and I suspected he actually never mailed anything at all. That's the two times I payed for something that never amounted to anything. There have been a few returns of payment for items that never turned up, always excluding p&p. Once a seller shipped an item a second time when the first one didn't appear for weeks, and after a months the second shippment arrived it w appeard in my mail box. Seller told me to just keep it. There's still a chance it might arrive, but it is a bit worrying when seller doesn't reply to messages
