For me it wouldn't matter - Janome and I do not get along. So I agree with those who suggested that you really need to test drive.
The APC (Automatic Plate Converter) is one of the main reasons I bought my 7700, along with the larger harp space, better lighting, and free arm. My dealer also made a point of telling me that with the 7700, you can stitch off the fabric, as in chain stitching, without getting thread snarls. I never had the 6600 so didn't know that was a problem, and haven't heard it elsewhere so don't know about that. Anyway, the 7700 is a great machine and I think it's worth the price difference you quoted.
