Ok, so my first (and only) incubator is a hovabator that we picked up slightly used. Have so far had 3 great hatches from it. Now I read that the hovabator is not great! Now that I know that, I am sure it will sabotage my next hatch. So I'm thinking of modifying/updating it. Can't afford to buy a fancy big one (wouldn't a sportsman be great?). Seems most people don't like the wafer thermostat. I have read that you should replace the wafer frequently, but can you improve on the entire rig? I saw somewhere someone suggested replacing the thermostat with a GQF solid state thermostat. Has anyone done this? Why is it better?
