IMO you have probably missed an exceptional secondhand deal. Who would sell a used Dave for €2k?
TBH I don't think there is a huge secondhand market for fake Daves...
I actually got in touch with the guy (couldn't help myself, was feeling cantankerous!) and exchanged some chit-chat. When I asked why, he said he was selling it cheap as he wanted to buy a new pair of speakers quickly, and it hadn’t sold at a higher price. He said he could take a photo of himself with his family so I knew it was legit (!). I countered with can you take a photo of yourself next to Dave, holding a bill or official letter that clearly features your address and the serial number of the Dave, before I make payment?
He went completely quiet after that.
Funny that........
Hope there’s nobody out there that actually falls for this.
