I own a Mares Proton Xtreme for hte cold water stuff and it has never frozen. My last cold water dive was in about 39 deg of water (which is about as cold as I care to dive in). Aside from that I have used my SCUBAPro X650/Mk25 cause it breaths so sweet but it actualy froze-up once.
I just purchased a Poseidon Jetstream but have yet to try them in cold water. I don't have any real reccomendation for anyone specific reg. I do however suggest that you stick with the ice rated models from any of the brands our peers have mentioned previously in this thread. Good luck and great diving!
