If you want ULTRA budget, I’ve used this cheap ass keyboard daily for 4 years now: https://www.amazon.com/gp/product/B07CLYNW78/
I’ve beat the crap out of it (literally, nodejs be frustrating af sometimes), but it’s still good as new. Some of the switches I’ve swapped out for Silent Black since my newborn was sleeping next to me at the time, but the original switches all work fine. It’s got all the RGB bells and whistles, but I leave it on white.
Good for them.
