Im getting my first 3D printer. My budget is around 400$. Any recommendations and things I should consider?

I will be using the printer to make cases for my printed circuit boards. Heart rate monitor casing, digital watch type casing, small electronic device custom casings. I need it to be at least a nice sturdy plastic that can survive being dropped on the floor without breaking. I dont need crazy detailed accuracy, just a decent amount of customization.

I dont care about how long it takes to print. I care about reliability and consistent performance over time. I appreciate any advice anyone has to give. Thanks.

So far I am looking at the Centauri carbon 2.
