That'd be a really crappy deal if you got a mark II. I got in on one of the Beach Camera Ebay deals and got my 5D Mark II and 24-105 for $2400.
5D MK II with 24-105 L IS for $2400 is a great and believable deal.
B&H has the 5D MK III with 24-105 L IS for $4098, which is also a really neat deal coz one is basically getting the 24-105 L IS lens for just $600
5D MK III, 16-35/2.8 L II, 24-70/2.8 VC, 24-105/4 L IS, 70-200/2.8 L IS II, 100/2.8 L IS, 40/2.8, 50/1.4, 85/1.8, 150-500 OS, 600EX-RTx2, ST-E3-RT, Rokinon 24/3.5 T-S, D7100+18-300 VR, YN568EX, 055CXPRO4+468MGRC2, 190CXPRO4+322RC2, Gorillapod Focus+496RC2, CamRanger, B+W filters, Konova K3/31.5 etc
