At least the OP is getting some traffic to his thread I guess
On the surface this appears to be just as trustworthy as any other remote purchase.
For what it's worth I bought my TAF from Italy from a private seller. He took a load of photos of the machine, and of various stages of it being packaged up, and being loaded onto the truck, etc. It turned up fine, and I saved at least £1500 on a comparitive spec one from over here.
That being said I'm not sure I'd do it again for several reasons. The main one, really, was that in my limited experience these conversations get to an awkward point where the buyer and seller know that because neither know eachother there is no implicit trust, so the seller wants to make sure they aren't scammed, and likewise the buyer doesn't want to send X thousand and risk the seller disappearing. In my case the seller wasn't interested in using escrow, perhaps because he didn't trust it, nor was he keen on a 50/50 split of payment up front and on delivery, I guess because - like him - I could just vanish once the pin has turned up. In the end I wired all of the money as he requested, and wrote it off in my head in case it ended up being a scam... That was a very uncomfortable moment for me.
Secondly, although the guy packed the pin really well and strapped it down, when it got to me the straps had gone walkabout and were it not for the very considerate UK driver who noticed it was unstrapped when he picked it up, and secured it against the side of his lorry it probably would've toppled over, with whatever damage that would've caused. The driver said it wasn't unusual for straps to go missing between depots. I had pretty much no idea where the pin was after it left Italy too, I just randomly got a call one day to let me know the UK logistics arm had it and when did I want it.
In my case everything panned out well, the pin was as described, it actually turned up and I wasn't out several thousand pounds with nothing to show for it.
I'm not sure I would recommend buying sight unseen for end users without the technical know-how to fix what might get broken in transit. My TAF experience was super stressful from the moment I paid for it up until the point the machine arrived. For people who do international logistics regularly, or for traders or experienced pinheads I imagine its no big deal.
That's not taking away anything from
@ababapanos's deal which looks to be a great one. Fingers crossed it works out for someone here.
