I paid $75. Nothing digital here. Couldnt find manual on it either. But i really dont need one. Temp adjustment is on top with tiny screw, easy. This older octagon 20 has the auto turn cradle I really needed. Im not home most days to give eggs attention. I have a hatcher that just sits there. The fan that is a bit louder than I would like. Dropped oil on fan pin which helped. Unit is in our bedroom because its the warmest room in house. The handle area on top where fan motor is located gets a bit warmer than I am comfortable with. But, if this old thing continues to work like it has been I'll be very happy. These eggs should hatch the 3rd week of Feb.
