Can't agree there.You need to look a bit more.
Sac 10's aren't out yet so no images for comparing, look for a similar size chiped Star light express images .
They more expensive here in OZ but are using similar size cooled chips as the SAC 9 10 11 12 and 13.

Have a look and compare the colour range and the imaging times .No waiting for CMOS to cool here.
Cooled CCD's give better quality with less noise and better sensitivity images in less time than un cooled CMOS chips in DSLR's.
You want to go deep and i mean truly deep in less time then cooled CCD is the way to go.
True the Modified DSLR's are giving good results but i said modified.You need to remove the IR blocking filter to get the full spectrum back into the images.There lacking the deep reds of an un filterd chip.
I don't think there would be such a large Cooled CCD market if they didn't perform.
