three budget custom keebs, under $200 

Keyboard #1 Ikki68 Aurora:
It goes up for sale pretty regularly and is my personal favorite. Tons of ways to customize the build without the need to buy extra stuff, like gaskets, foam, etc. This particular layout may not be for everyone though! It's also hotswap & lightweight.
Keyboard #2 QK65: PS I LOOKED AT THE WRONG PRICE FOR THIS its 150, see the pinned comment!
The new hype for budget custom keyboards. By far the prettiest build & it also features lots of stuff in the box to help customize the board. This was the nicest sounding board out of the three and easiest to build. I also loved the finishes it comes in.
Keyboard #3 Zoom65:
To me, this was the weakest of the three boards as I found you almost needed the included foam to reduce the thin sound profile when using no foam. It did have a nice typing feel and cool finish, but it didn't feel as premium as the other boards.
