Many thanks, Ray. Very helpful information and very balanced too. If you have time to look at sky brightness in your model I'd appreciate your sharing of the result.
Cooling wasn't mentioned. Seems the Sony CCD doesn't need nearly as much compared to the Kodak chips. I looked at several offerings of the KAI4022:
FLI cooling to -55C below ambient
Moravian -50 (2 stage)
QSI -40
ATIK -40
Starlight -40
The Moravian camera is attractively priced and includes a built in wheel, as does the QSI which offers guiding options too at a price.The FLI, I'm sure offers other electronic benefits as well as the best cooling, but is quite expensive in comparison to all the other cameras.
I'm a sucker when it comes to "new" technology; consequently the 694 CCD cameras won't get out of my head very easily, in spite of rational and tested competition....
