I was thinking about hatching around 12 eggs but i dont want to buy a pricy one and cant find a good used one. I want to do this to be more sustainable and for fun. Also since i dont have a roo where should i buy hatching eggs.

It is a Little Giant but my mom has used one of these for years and had no problems with hatching with it.
The older style I guess are better.. idk since I haven't had the older ones..
The new ones are digital and the temps vary wildly..
Do you have a second thermometer? Is it checked for accuracy?
If so place it in all 4 corners for awhile to check for various temps.. I've found that temps are wildly diferent
I do have a second thermometer in mine. Maybe that's why it works for me. I go by what the second thermometer says. Habit really. I just adjust the incubator temperature until I get it to the right temp on the other thermometer. I like the digital because to me even if it's off it usually isn't more than about a degree and for me the digital is easy to adjust. My mom has one of the older one and a digital and I do think the older one is slightly better, but for just a cheap, hatch my own backyard eggs I have found these work.
Well that's what we all do ..is set incubator to the thermometer that's tested..
What I'm trying to say is since the heater is not in center.. the temp vary wildly.. sometimes 3 or 4 degrees diferent. . You will only know if you test all areas with your thermometer.
Some people report better luck if the rotate lid every so often .. but personally if I was buying one.. I'd go with a better one...
