shoenberg3 -- I'm not really enjoying being Mr. Buzzkill here. I've owned the 1Ds, 5D, 1Ds2, 5D2, and 1Ds3, and used the 5D3. Each of these had noticeable (if incremental) improvement of IQ over the original 5D (which I owned the longest of the others). I understand what you mean, and I'll estimate the 5D3 is double the resolution of the 5D, but that is not nothing. It's a significant improvement, besides the AF, noise and banding.
I do agree -- Anthony likely needs to improve his glass. But he asked about cheap body upgrade, not glass. I've got a feeling he could do better with improved PP techniques and L or top Alt lenses. But now we're not talking cheap at all.
