I would search so many place but I can't find .co.in domain name. Anybody know where can I get .co.in domain name?

You can get one from here : http://www.indianregistry.net/coin/index.htm

Or you can register it from here http://www.domaincentral.com/

Which is better .co.in or just .in for SEO
also please tell me cheapest registrar which offer both .in or .co.in........:)

Still no experience of .co.in and .in TLD domains but I think .co.in domain names better then .in domains.

Here are domain registrar who provide .co.in and .in domain names.
