Congrats Nadeem, Buyer must be some millionere Arab with oil factory/ies and definately you can pull more for that name i mean if i am millionere and my own name dot com fancy me i would not hesitate spending big bucks for my name dot com. You might not be able to find BIG potential customer like that again if you decline him.As wwwdomain said give it proper media coverage and get it sold, you would earn a goodwill and name which might end up getting you more customers and definately you can spend that decent sum of money on buying more generics and sell them each for $70k or more after next few years or invest in your business which ever you prefer.But apart from all that just think for few moments that would you be HAPPY after giving away that domain or you would be UNHAPPY after declining that offer ? hope you get the point and best of luck
