I have 2 x novatel OEM615 receivers, one with roving firmware and another for the DGPS base station.  I also have a 600-LB L1 L2 Pinwheel antenna.

Each receiver cost $3500 and the antenna $1000.  I'm willing to sell each receiver for $1000 and the antenna for $500 each or the all of them together for $2250. 

You can read about the receivers here :
