The Amazon Kindle isn’t available to India, see the question "Is Kindle available to customers outside the United States?" here:

So even if you can get the device, it will be a headache to get the books on it, as you still need a US credit card and shipping address with your Amazon account in order to get the books.

I’ll suggest you to go for the Sony Reader instead, which is the best alternative of the Kindle. There is a good review here:

You may get the device from Amazon too. They provide international shipping at a reasonable price.
