Quality doesn't come cheap. I know people have had success with Hova-bators and the Exo Terra ones, but I wouldn't risk it. Which is why I built my own and made sure it was good to go before I got eggs. Other than that the only incubators I would look at are Hot Box Incubators or Nature's Spirit. Idk how expensive NS is but Hot Box is a pretty penny, and they don't have any single or double clutch incubators. I think their smallest one is for like 9.
