I was researching for budget-friendly, "thocky" mechanical keyboards, and the AULA F75 was one of the top suggestions. EPOMAKER is currently running a sale with better discounts on other products. My second consideration was the AK820 PRO, which is now available at a 20% discount. The 75% layout is highly preferred within the custom keyboard community.
The LEOBOG Hi75 is highly regarded for its excellent quality and aluminum alloy construction, but it is a wired keyboard.
All these are Hot-Swappable(you can easily change the switch and key caps)

I have two of the Epomaker TH80 keyboards and they failed within a year where the PCB had failed by a component burning out. Epomaker did send out a replacement PCB, but they wanted me to pay for shipping! The replacement board also failed. So not a fan of what they are using as a PCB supplier for their keyboards.
Instead, I'm using a wired keyboard now (Monsgeek M1) with no issues and it has been super super super reliable!
