wow. now my camera has officially depreciated 1k in just about 8 months. Early adopter penalty.
I bought this camera back in July for $3499 as well, i feel your pain! Granted I did get about $200 cash back through best buy but $1k off is even sweeter. This camera is AMAZING, if you are on the fence go for it. There are some really killer deals for the 5D Mark II refurb as well but this has 3+ years of technical improvements plus 7D-type auto focus, IMO i think it's worth the upgrade. Use ebay bucks/discover cashback for even sweeter deal.
