I have the Yescom32. It is cheap and has some flaws but we've made it work.
The pros are it has auto turners that work well, holds 32 eggs, has a fan, and digital temp and humidity.
The cons: The lid doesn't seal tightly. It's a flexible piece of plastic. My husband made me a gasket to help...
I have two black Swedish girls that are two years old and the most they ever fly is from the ground to their pool: about two feet height total off the ground. I seriously doubt they can do much more - or care to.
