Again moot IMHO.

SBIG have a (not often menioned) patent on CCD chamber temperature that allows them to hold it to with 1/100th of a degree of the set-point.

This allows for very accurate dark-sub calibration....which is going to clean up an image way better than a few more degrees of delta-T based on an unstable set-point.

Having used ST, STL and STX versions of their products...that latter having a massive delta-T capability if you choose to run liquid cooling ..I can not say I've not much difference between well calibrated frames from one model to the next.
