I bought my Airmap 1000 from Avionics West a while back for this price, and I could not be happier. I have flown with a lot of different equipment, but you cannot beat this price for a huge screen like that: http://www.avionicswest.com/airmap1000.htm#2003

Tom, the owner, is such an honorable person to do business with. Very down to earth and patient and friendly. I'm not affiliated with them either. He's the guy that writes the tech avionics articles for the Cessna Pilots Association.
