There is a certain domain i'm planning to buy at an auction.
Its an exact keyword match '.com' domain.
The keyword which it EXACTLY matches has the following monthly global search volume :
Google - 159,000
Yahoo - 82,000
Bing - 41,750

How much should i pay. The current highest bidder is at $24
Sorry i can't mention the name, but maximum how much would you bid if you were me.
I have done some SEO analysis on that keyword and competition seems to be natural(competitors haven't done any SEO for that keyword) and not optimized, i.e. it shouldn't be too difficult to reach the top.
