Thank you for your reply, PeopleNet. Appreciate it. Yes, I do feel that SugarFree.in has got good potential. Estibot values it at $1500, but I guess it is worth more.
The only problem I foresee with this name is that Sugarfree is a trademarked name from what I know. Developing it could lead to some legal hassles. You would be better off trying to sell it to the Cadila group which owns the brand.
I had approached Cadila a few weeks ago, even before starting this thread, but the deal did not materialize. But I am planning to keep this domain because IMHO, it is a valuable one.
As regards to TM, i did some research before approaching Cadilla, and although I am no attorney, I did realize that keeping this domain is not an infringement of their copyrights.
PeopleNet, thank you for sharing those three links. They were informative.
