I have been asking myself this same question. 1DIII or 5DII. I have found prices for them between $1,999-2,099. The 5DII being the more expensive of the two and if you consider the battery grip you can add another $250 to that price. From what I have read the image quality is near the same, the 5DII doing a bit better at those high ISOs. In my mind it comes down to Video Recording (which is limited without and auto focus) and a weather resistant body with built in grip and more room on the back.
Personally I haven't figured out which I am going to pick up yet.
What currency are you talking about there?
I think if you can find a 1DIII from a reputable source and in good condition for the price of a 5DII, it is probably a better value (unless you really need the resolution or FF).
