Thank you for your time and your recommendations.
I've not been sitting on my hands in the meantime and had to realise that MX switches seem to be a top shelf product as far as ready assembled 100% keyboards go that are still in production. Honestly, I would not have guessed that.
It seems that when you're looking at a backlit board with doubleshot PCB caps and a decent switch type,
we're not only talking about a small fortune, but also some research to find the fitting parts, plus either assembling them at home or paying someone to do it.
I would say that you are conflating two different things here.
Stock Cherry MX switches are designed for reliability, affordability, and ease of production. 'Tactile sensation' appears to have been a more distant consideration.
You can buy a very nice Cherry MX keyboard off-the-shelf, for an affordable price, if you are satisfied with the feel of stock Cherry switches. For example, you can buy a very solid Leopold keyboard with PBT double-shot keycaps, detachable cable, sound-dampening materials, and other features, and have it shipped to your door in the United States for $124.
For $25 more, you can get a Varmilo VA108 with LED backlighting and four extra shortcut keys. So, what I'm saying is that you can get some pretty solid MX keyboards for $125-145 shipped. Cherry MX can be mass-produced and give you good value.
However, if you are not satisfied with the feel of stock Cherry switches, such as MX Brown or MX Clear, then we are in a different territory. Now you are talking about
custom MX keyboard. And yes, this becomes a "top shelf" item where the sky is the limit in terms of cost and quality.
If you want something better than MX Brown / Clear, you are going to have to pay. Now, it could be a low price, like getting a GMMK and putting custom switches in it. That costs about as much as a Leopold / Varmilo.
But if you want something with the build quality of a Leopold / Varmilo AND custom switches, you are going to pay money. The fastest / most cost-effective way to do this is ordering something from the Varmilo custom store. You will get a Varmilo with your choice of lighting, keycaps, and switches, although they only offer a few custom switches, such as Zealio 67.
Or you can go the full custom route. The introductory models, using custom switches, cost a little less than or the same as a Leopold.
So if you want a quality MX switch in a quality MX keyboard, you are going to have to
PAY.
