I think the long and short of incubators are the cheaper ones make you do more work and the fancy ones automate the work. For example, mine was 80-90$ (new, but I'm sure SO found it on some sale somewhere), but you can set the temp, it has a temp alarm, tons surface area for water, a hygrometer, a humidity alarm, and it rotates the eggs every 2 hours. (plus it has like a 48 egg capacity so you could definitely get a similar smaller one for cheaper than than).
You can get one without all those fancy things and turn the eggs manually yourself 2-3x a day, check the temp and humidity on your own, etc. But I really like all the features. Theres already enough troubles to hatching eggs. I'd rather know that my incubator will scream at me if something is super wrong and has everything automated in case I forget to check it. Haha.
