Is this your first camera? the 6008s is a great camera, the 6008pro even has crystal-sync, but the Bauer is a good camera to consider. And it has a really neat matte-box that should come with it. But I doubt the 6008s is worth three times more than the A512. Both cameras have a variable shutter which produces very crisp images (unlike the blurry ones from a XL shutter) and both have many options. The beaulieu has both forward and reverse operation. The 6008s has a C mount and you can find a Angenieux lens for cheap on ebay.
