I have a old 1602 from GQF. But the styrofoam is old and dirty. So since i will be getting back into poultry next year i want to buy a new bator. What options do i have in the less than 200$ price range that is made out of plastic. Should hold atleast hold 5 chicken eggs, more would be awesome. Which ones have preset thermostats, i had issues with my GQF
