In my opinion, the Sportsman incubator from GQF is by far the best. I have used the foam incubators and never had great hatches, except in my Sportsman. I have the electronic multi-turn thermostat and it holds the temp exactly where I want it. This one you can set and forget. I remember one year I set about 150 eggs and did actually forget the lockdown date. When I went into the room I had chicks everywhere in the unit. Even though they hatched upright and the turner was set at a 45 degree angle, not one chick was lost.
