Thanks Don for the reply, and I might make my own. The problem with the Reptibator is that setting it to 97, gets me about 90 degrees at the egg level. This I believe is because the built in thermostat is set right next to the heat source, making it not the same temp as the eggs. Also do you know if there is a way to tell by the eggs if it is to hot in there for them? Maybe they will turn yellow or something? Thanks
