Also, please consider the fact that for proper film scanning, the LAST thing you want to use is a flatbed - any diffusion between the film and the CCD or CMOS, such as, say, a plane of glass, will reduce the quality of the resulting scan. I used to run into this pretty regularly when working with 35mm negs vs. medium format negs; the 35mm stuff was done on a Nikon film scanner (no glass), but the medium format stuff had to be done on (a very nice I'll admit) Canon flatbed. No comparison at all.
The issue with the GOUT isn't just the stabilization. There's also been a hell of alot of damage done by the NR smearing and odd interlacing. No amount of processing is going to fix that stuff (I've done all three movies through the 4.02 script, and, while a great improvent, you can't create detail where none exists).
