One of the best deals around right now is a brand new 5D Mark II. Canon just increased their instant rebate price significantly, so you can pick up a new body for $1799. That's also going to push second hand prices down quite a bit too, you might be able to get a used 5D II for around $1300. The image quality advances of the 5D II over the original 5D are significant. The 1D Mark II you reference is not a full frame body, and I would prefer even the original 5D over it. The 1Ds Mark II is full frame, but is not as good of a deal as the 5D II right now.
