price wise you can`t go past the still air hovabators.was looking at the rcom reptile ones for $650 on Tm but it was the old story of if it ain`t broken why fix it?Have used everything homemade,tanks within tanks,waterbed drawers,hotwater cuppboard etc.The incubator is only as good as the room where you choose to set it up and for temp determined sexing which I assume you are interested in,this can be critical.Mine are setup in a wardrobe on the coolside of the house but here in hawkesbay they are always sneaking up??
