What do you think of using a CO2 incubator for incubating eggs? We use them in the lab, and they are excellent at maintaining temperature. The only problem that I can see is that there's no window... Thanks !! http://www.swicoauctions.com/viewItem.php?itemid=72396 ETA : I searched for one new, and they typically run around $3500... but it would do a lot which I didn't need, either.
