With three different addresses I would be skeptical about them.
Maybe you need to confront this NICE person you have been talking to and ask him about all these different addresses on different sites and let them know that you have investigated them a little.
Would like to hear his response.
I got a quick reply which said that
'The projectors are made in China, mainland China. We are in Shenzhen, a city in the north of Hongkong. Our forwarder will ship the goods from Shenzhen to Hongkong first, then TNT Hongkong will get the goods on board their flight and send the goods to UK'
which seems fair enough so I shall still take the chance and get the projectors. Hopefully I am right as the projectors are pretty nice for the price and they do some other items I am interested in as well.
