What is 6% of $250,000?

 I read this
blog entry from Chris Sells
recently, describing his thoughts about real estate
agent fees.  Having just sold one house and purchased another, I am completely
sympathetic.  6% just seems like too high a vig to pay, just to sell your house. 
You can FSBO, of course, but ‘they say’ that it takes much longer to sell
when you do all the work yourself.  Anyone have actual experience with that?
