There are Few Issues with it.. 1st of all max of the Comanies doesnt ship to india !!! Now if you can over come that issue then a bigger problem comes with warrenty... as suppose u are buying one C2D from USA, now Warrenty would only be valid under USA... so when some thing goes wrong with the hardware you have to ship that Hardware to USA and bring it back under ur own expense...
2nd big problem is Customs... They can hard judge what the matter is, and u can end up with a custome bill which is valued more than ur Product ... in my case I had no option of Buying TherMalRight Ultra 120 eXtreme so I had to order from USA, for a pice of metal I had to Pay Rs. 800 as Customs Duty !!!
