I always buy directly from China.
Either from Tmall.com using an agent, from AliExpress or some webshop (tip: search thru webshops using chinaprices.us , for example: buyincoins or banggood, you can even apply a discountcoupon).
Guarantee and delivery wise of course it would be more convenient to get it from your own whereabouts, but consider the fact that the reseller has to calculate that in as well, so with service costs and profit margin the price will go up quite a bit compared to getting it yourself. And there's only a slight risk something's wrong with your unit and having to send it back. Personally haven't ever have to do so.
So not having a reseller in your country, to me, doesn't sound like a dealbreaker at all?
Maybe it is just the luck of the draw for me, but I have sent back three tabs ...with mixed results. One was actually stolen en-route back to China, so it was a total loss of well over 200.00.
Actually I did not expect the last one to give an issue ..the Ramo W42, but it did. What can I say? It is in route back to Lightake as I type.
I have been very prone to ignore suppliers like TNT, as I was more interested in cost. But then I began to realize I was actually looking for a quality, well outfitted Android tab for less money than an OEM. I was not looking for the cheapest tab, but a better one.
When I factor in I do not want the OEMs 10.1", 7" and 8" sizes, it became increasingly clear that a good supplier like TNT might be the answer. The 9.7" and newer 9.4" are surely my cup of tea.
I surely have spent enough on postage and losses to make the extra 40.00 or so a viable option.
