https://falba.tech/ and https://keycapsss.com/ are two suppliers in Europe, both sell kits and the first sells premade keyboards.
There are small companies selling prebuilt keyboards and kits elsewhere, but I don't know them offhand, except for https://www.aliexpress.com/item/33006060286.html from China (as I have one). There's also https://www.reddit.com/r/mechmarket where there are people that will build the keyboard for a fee, or sell keyboards second hand.
Then there's the larger operations like https://ergodox-ez.com/ and https://ultimatehackingkeyboard.com/ only selling built keyboards.
The Reddit wiki is a reasonable reference, and the Xah Lee site it links to: https://www.reddit.com/r/MechanicalKeyboards/wiki/buying_gui...
Overall, it's pretty great; if you don't want to build your own, and if you don't want to change your keyboard, it's the best choice because it has been in production since the early '90s with few changes to layout; for me? this is big- changing layout is a big deal. The kinesis has been in production long enough that I am pretty confident I won't have to learn a new layout until keyboards go by the wayside
It's probably the least portable keyboard I've owned, though.

You can get them next-day from amazon, too, which is nice for essential parts such as these.
Regular keyboards start giving me fatigue after 20–30 minutes, but I type on these all day, all week without issue.
Some cool features:
- you can use arrow keys without moving your hands from the home row!
- with correct posture, it’s possible to hit every key on the keyboard without moving my wrists (though I have long hands)
- fully remappable keys, built-in
- includes some extra key caps so you can customize the layout in the thumb area
- it has a “numpad mode” that can turn the right-hand side of the keyboard into an ergonomic numpad
One model that's easy to find assembled is the Ergodox. But it's been improved by new models like the Iris, Corne, Gergo, Kyria, Lily58…
It's fantastic and highly recommend it.
