I'm mildly interested in keyboard ergonomics and efficiency, but every time I read threads like this I can't really see me spending $200+ on a keyboard when there are quite functional versions at $10 (and I know that the vast majority of the world is typing on either those or a laptop keyboard). To me it reads too much like an audiophile discussion about whether the materials of the cable affect sound, or just people "playing" (similar to cyberdecks). Not just trying to be provocative here, but those prices just seem crazy and just Silicon Valley posturing. Is there a post here that is not partially signalling "I'm rich enough to splurge in an unreasonably expensive set of keys"? Or am I being too harsh? The most grounded take seems to be easterncalculus's "https://news.ycombinator.com/item?id=47083354" where he mentions that the best approach is to rest and exercise a little bit instead of having led-colored chording keyboards.
Sorry, I'll go get my coffee now :)
Mechanical and Ergonomic keyboard prices suffer because they are niche and way lower volume. The switches are not that expensive if you use common ones, but if you want some special keycaps, prepare to fork some good money. Most of them are made in very low batches and most of the expense is in the molds you have to make. Your $10 keyboard is probably so mass produced that literal millions have been manufactured. Versus custom-ish keyboard designs that are made for at most a thousand buyers.
It's very much a hobby, like audiophiles, but also like tricking out your car. It can be expensive. It's more than the average person needs. It's fun picking out parts and being part of a community.
There's also a perspective bias that most mechanical keyboard content you see is not made by people who found a keyboard that made the wrists stop hurting and then went on with their life. The people enthusiastic enough to make content are also the people that have a bunch of tricked out keyboards.
There are much cheaper Microsoft ergonomic keyboards, even if the 2 keyboard halves are not separate, so you cannot adjust the distance between them or the lateral tilting.
I had been using for many years Microsoft ergonomic keyboards and it was still much more comfortable than with a classic keyboard.
A few years ago I have switched to a really split keyboard (Kinesis Freestyle), which was an improvement over Microsoft, but not a so great improvement as Microsoft was over a standard keyboard.
Unfortunately, Microsoft has first discontinued their cheapest ergonomic keyboards, which had almost the same price as standard keyboards. Then the remaining more expensive models have been sold to Incase in 2024, so they can now be found "Incase Designed by Microsoft" products, but at significantly higher prices than when they were made by Microsoft. Even so, they might be the cheapest ergonomic keyboards of decent quality. Microsoft still sells a "Microsoft Surface Ergonomic Keyboard".
Old stock cheaper Microsoft ergonomic keyboards may still be found at certain shops.
On eBay and the like a lot of old and very cheap Microsoft ergonomic keyboards can be found, but buying a "pre-owned" keyboard is risky, as you do not know how worn out it is. Moreover the wireless MS keyboards used proprietary USB dongles paired with the keyboard. If an old wireless keyboard is sold without the dongle, it cannot be used unless it also has a wired connection.
For someone who types all day, there is a great difference in comfort and fatigue between a classic keyboard and a good ergonomic keyboard. Young people typically do not care much about the quality of their keyboards, pointing devices and monitors, but after decades of using computers every day many of them regret their negligence, which could have avoided unpleasant health problems.
