Harsha, that's great news. I knew that was a cool name when I first saw it.
I would consider selling for $400. That's a fair price for the Indian 'wholesale' market, reseller to reseller. If you need the money for other renewals or purchases, go for it. Good luck!
I get $XXX offers on similar 3 letter Indian domains all the time from other resellers. I've sold off quite a few of them when I needed to raise cash, but I'm still holding a nice stash in hopes of future sales with an extra X added.
