I’ve used a Kinesis Advantage at work for 7 years now. Started after I began to get wrist discomfort once I started programming full-time. It’s been wonderful, and removal of the discomfort and pain is worth the $300 several times over. I bought one for home shortly after. It does take a bit to get used to typing on. It took a few days to get from 6 wpm to ~35 wpm, and about two weeks total to get to ~80 wpm. I can usually type a bit faster on a “standard” laptop keyboard, but 80 wpm is still plenty fast. I’m a Vim user, so I mapped the End key to Esc (keyboard has hardware mapping built-in).
I do experience the stuck-key issue referenced (annoying, but easily worked-around and infrequent), going to look into swapping the PCB as linked.
I wish there was a way to try this keyboard without committing to buying it for a month or so. It seems like there will be a learning curve and you might not even like it at the end of it.
