If your goal is to make mini figures, what you want is an SLA machine. They are much better at making small detailed objects than FFF. However, it will definitely cost more than a cheap FFF machine like an Ender 3.

The Ender 3 variants are cheap and a great platform if you are OK with tuning/tweaking things. If set up properly they work great and are pretty reliable. But of you want something that works out of the box and doesn’t need any tweaking/tuning, you will probably be disappointed with it.
