Ebay (via Roberts Camera) currently has refurbished Nikon D4 cameras for $4,249 with 180 days warranty and free shipping. This is a pretty good deal considering the original D4 price ($5,996.95) and the current D4s price ($6,496.95). FYI: Amazon still has some new D4 cameras in stock for $6,199.00 (via third party reseller).
