not just any camera

i want a new camera. not just any camera but the canon 5d mark 2. how??? i have not even purchased most of the lens on my wish list and am now eyeing a new body. *sob* went window shopping (again), and saw that the price for the 10-20mm lens has not reduced any further. of course if i were to be totally honest to myself, the lens would be a much better purchase. i already have a bloody body. i need the lens more than i need a new (and extra) body. additionally, the 5d mark 2 would cost more than 2 10-20mm lenses. what do i do? in a perfect world (or my world), i can actually own the 10-20mm, plus the 5d mark 2, and then some.
