You have not mentioned which model camera you have bought so it is difficult to say anything of real value.

I'm not keen on water sitting around the observatory in a bucket or such, or long lengths of water tubing. The SBIG pump solution seems like a bare minimum in that respect really, not a neat solution. I much prefer the idea of a closed loop system where an air cooled radiator keeps the water at/near ambient (but doesn't go below ambient, because at best its being cooled by ambient air). It's this kind of solution I was thinking of.
There are stats out there suggesting a cooling improvement of 10-15 degrees which sounds worthwhile when the camera is only at zero degrees. I'm interested to try it, but I completely see yours (and others who have PM'd me) point that it ends up being more trouble than it's worth and wouldn't be surprised I put it in that category too.
Thanks,
Roger.
