Gadgets in Thailand are way cheaper than anywhere else but, there's a small heads-up - more than likely, it will have a CSC code for Thailand, Asia, so the updates on that would be somewhat, slower than the rest of the region zones.
Having said that, you can flash it with a different regional CSC code. So go for it, when the first Samsung Galaxy Tab 7" (P1010T with Wifi only) came out, it was on sale there in Thailand - a mate of mine was there, and got it for me - 200 euros - it was a steal, it would have been about 450euros to buy in the EU. And yes, it was genuine, the real thing! :)
