I would go with either a Brinsea Mini, or a MagicFly 12. The Brinsea is a bit more expensive, but it will be way more reliable. If you don't get eggs often, you'll want a more reliable incubator. The MagicFly is cheaper, but it will probably end up costing you eggs and time, because it needs almost constant monitoring, and you'll probably lose a lot of eggs trying to figure it out. Once you figure it out, it will be somewhat reliable for a while. But then will start to go downhill, and need recalibrating all the time. After a year, mine started having crazy spikes, despite the exact same set up. So, I would probably have to recommend saving up for a Brinsea. The heartache is not worth it, trust me. If you have a lot of invaluable eggs that you can test the Magicfly on, then it might be ok for a year or so once you figure it out. I used to swear by mine, anything I put in it once I figured it out would hatch. Then, just before lockdown, it spiked to 108. It fried all of my really valuable eggs. So I got a NR 360. I would suggest it, but it holds 22 eggs. It's more than you need, but about the same price as the Brinsea Mini. You don't have to fill it up.
So consider the Brinsea Mini and the Nurture Right 360. If you're located in Africa though, I don't know how easily you'll find either one.
Good luck. Let me know if you have any more questions.
