Forget DSLR cooler boxes, they don't work. I built one some years back, and it was well built, insulated, sealed, etc but for cooling to be effective it has to be applied to the back of the sensor. Much of the heat generated in DSLR comes from the processors not the sensor. External cooling, aka a cooler box, is great at cooling the outside of a camera but the inside remains warm. You might get a few degrees of drop but imho its not worth the effort. You need to consider the weight of the cooler box, TEC, fan, copper plates under the TEC (aluminium sucks at heat transfer), and the control circuit required to power it.
I came round to building a couple of cold finger cooled Canons and they are magic.
Finally the ASI1600s are good value package in a small form factor. It seems ATIK has finally realised the market has left them behind, and are now trying to produce a 4/3 cmos camera.
