if your new to hatching, and just working with a few birds; Brisnea probably makes the best incubators. hovabator, and little giants aren't bad either, but wont last as long and not quite as "advanced"
if your flock is larger, you might look at Brisnea's larger incubators, or possibly GQF Sportsman incubators.
don't buy an incubator just for its digital readout, and never trust the thermometers and hygrometers that come with an incubator. just because its digital does not make it right, also just because its "old fashioned" doesnt make it right either. most thermometers digital or not have a few degrees of temperature variance in their manufacturing.
