Last year when our Thomson freeview/topup tv digital recorder packed up, I looked on Ebay for a replacement.
A chap was selling one on there which he had just bought new. He condemned it from start to finish, opening the description with "a completely useless, unreliable piece of cr*p, bought in error, anyone foolish enough to bid for it needs their head examined. Any profits made will go straight to Marie Curie Cancer fund".
It attracted a lot of bids and sold for £56! The buyer was warned!!
