URL: http://www.kidneystones.co.in Currently I have just bought the domain and setup a blog with a highly unique article written by myself on kidney stones in women. Because of the presence of "in" in the TLD it is best for some of the keywords like Kidney stones in women kidney stones in men kidney stones in children and kidney stones in dogs their url also becomes simple http://www.kidneystones.co.in/women.html and so on The site also has backlinks from a PR2 site and a few other sites which u can check in yahoo site explorer.
I think it is a nice domain had it been .in instead of .co.in then what you were saying about the TLD and keyword think, it would have made more sense to me. I think you should be happy to get mid $xx or a little high $xx IMHO I think you should develop the site. Good luck
Try to sell it seeking serious offers for it while highlighting its specialty. you will get an idea. its your wish to accept offer or not.
