I must say it does seem a little impatient. If he has posted it, then both you and him are at the mercy of EMS. If it's shipped via boat, then it'll most likely be in a batch. Could be that a batch was delayed or there was trouble at EMS's end hence the new tracking number.
To be fair, he has replied to you each time and given you all the info he has. If he was out to con you, he'd been long gone by now. Sometimes things take longer, I waited 5 weeks for some shirts to arrive with me from the US simply because the post got backlogged. That's just the way the world works.
With that in mind though, I bypassed Ebay and bought my Little Dot MK III straight from a Head-Fi member today for £120 shipped (he's British)
