Epomaker th40
Yeah that's one cheap board, rapidly entering the price point that it would be given away in a box of cereal. The detour I ordered last year was about three times that price without caps or switches and I consider than a bargain for a metal keyboard.
It seems to support Via, which you will find very useful to tweak the keymap to suit how you use a keyboard, using a 40 is all about getting the right map for your personal style.
Keycaps can be cheap, its like anything including the actual keyboard, you tend to get what you pay for, even if the increase in price is exponential. Signature Plastics keycaps typically cost me £200 ish for a full set to cover a 40 due to the non standard mod key and space bar sizes. I can buy a cheap set for like £20 on aliexpress, do I expect the same quality? Do I expect them to fit my boards that have unusual layouts? Absolutely not.
Thats the other thing with 40s, while boards exist that have full sized mod keys like the equinox, plenty do not. There are the compatibility three caps that tend to get added these days, that covers a lot of the more normal layouts. Having to get extra caps because you want to use less caps is irony at its finest.
I have never understood how switches can be so cheap full stop, especially ones with pre applied lube.
