Nobby, it is good that he is talking to you, lets take that as a positive. However, if he is out of work he must have all the time in the world to be making prop stuff?
Are there any members living close to him that can help out, i.e. collect the stuff, or he can ship it inside the us (less cost), then you send them the money to ship to the UK? Sending him more money, although I see where you are coming from, is still a bad idea. Maybe another alternative is to pay a courier such as DHL to collect from his address, if it falls through and you loose your money at least he did not have it?
Also, what is he making for you and is it coming finished? I have been reading the other threads and can't keep up lol.
