This page contains keyboard brands and makers I’ve had some experience with and my thoughts on each.
Epomaker
I’ve bought a few Epomaker keyboards, my main experience has been with the Niz Plum x87 which I’ve reviewed. My overall thoughts on Epomaker is that it’s a good starter keyboard brand, a bit pricey for some styles you can find on Amazon but they have a huge selection of pre-built keyboard with so many different layouts. If you’re looking for something weird and unique, they most likely have it.
