Hi webistin and welcome to INF!
I've merged all of your appraisals into one thread for convenience.
The one I like best of these is SalesManager.in. Sales are an important issue for every company and larger companies will need a well trained Sales Manager.
The domain would make a good portal with information about being a better sales manager, job listings, career advice, software sales, social networking and more.
For sale to another domainer, I'd say the domain is worth low $xxx.
