In addition to the following:
- customs duty on value of goods exceeding your allowance
- NTSC tuner on a USA TV vs PAL transmission in India
- voltage and frequency differences
it may be better to buy something local. Everything is available in India these days, and buying locally gives you the much-needed after-sales service when needed.
Unless, of course you are able to buy one for Indian specs in the middle east or Singapore/KL.
