I think it would depend on what you wanted to spend. My hovabtor Genesis 1588 with a 1611 automatic turner was $ 181.00 including the shipping. It was recommended to me by MissPrissy, one of the experienced moderators here.
1588 The Genesis Hova Bator picture window has a pre-set electronic thermostat. It is UL/CUL listed. 12 Volt DC power supply plugs into 110 volt outlet. My manual states it is preset at 100 degrees, and mine is holding at 100 degrees.
Here is more information from another source on the Genesis 1588.
The Genesis Hova-Bator is pre-set for bird eggs. Simply plug it in, then add water and eggs. Nothing to set up or adjust. This circulated air Hova-Bator comes with a thermometer, plastic bottom liner, and is pre-set to 99. F (38 C). Like all incubators, the 1588 requires a stable room temperature and should not be used in areas like sheds or barns. Being pre-set, this incubator delivers consistently good hatches.
-Although it is pre-set to 99 F, the thermostat can be adjusted. The 1588 can be set as low as 80 F. for use with reptiles.
-Soft-Air fan technology provides needed oxygen and refreshes air without forcing air directly on the eggs.
Dimensions 18' x 18' x 9 1/2' Without an automatic turner in place, the incubator will hold 50 large duck or chicken eggs or 140 quail eggs. 12 Volt DC power supply (included) plugs into 110 Volt outlet
This is the egg turner I purchased:
The 1611 Egg turner holds "42 eggs - any size egg from a partridge egg to a duck egg".
I ordered from
Smith Poultry and Game Bird Supply
I understand that Barn Basics may be about $25 - $30 cheaper so you could check their site also.
