Bit of back story: feel free to skip ahead…
About 15 years ago, I fell playing football and sprained my wrist. The pain continued for weeks, until I changed from using my laptop’s keyboard to an external Microsoft wireless split keyboard.
After a few months I migrated to a Microsoft Comfort curve 2000 which I preferred due to the more normal layout, but it still helped keep my wrists relaxed. These have been my daily driver for the best part of 15 years both at home and work until a few months ago when I bought a second hand Unicomp Model M, and caught the bug.. (DAMN IT!).
The Unicomp lasted 15 minutes, but turned out to be too noisy for my colleagues so has been relegated to home, where it’s been used very lightly in the evenings.
Having caught the bug I looked for an affordable mechanical keyboard for work and ended up with the Logitech G610 with MX browns and fitted orings to quieten it further…
However, having spent and evening racing on typeracer comparing the unicomp and 610 followed by a day in the office my RSI came back with vengeance by about 3pm and I’m stuck with the realisation that I probably can’t work 9-5 on a traditional keyboard. This seems to severally limit my mechanical keyed options and pushes the price up significantly from the research I’ve done so far, hence why I want advise before investing.
Question 1) Has anyone who’s suffered from RSI found an improvement moving from a full keyboard to a 10 keyless mechanical ?
If so, a cherry clone Drevo 84 could be an option to try this out. It’s cheap readily available in uk.
However assuming I do need to go split, I seem to have only a few choices inside my budget and design requirements.
1) ISO layout. I can’t get used to @ and “ and # being in the ‘wrong’

2) I need direction arrows.
3) I prefer tactile switches.
4) Must be moderately quiet. (no bucking springs or clicky unfortunately)
5) I can’t justify over £200 (yet….)
I’m really struggling to spend up to £150, but if I know it’s the right board and it’ll last me 5 years + then I will commit.
6) I’m UK based. (and impatient)
Self Build
One option seems to be to build my own, which is something I’m quite interested in, but I need something now and can’t wait for parts or build times. So this may be an option in the future but isn’t an immediate fix.
The ErgoDox type clone builds look really interesting and is probably what I’d aim for but maybe with a nav cluster.
Wanting something quickly due to ongoing RSI my top shopping list item is:
Matias Ergo Pro – seems like the leader to me at the moment. It’s tactile and quiet and split and has arrow keys and UK layout. But it’s a lot of money for something I’ve not tried.
Truly Ergonomic 227 and 209, were US layout, so I ruled them out but that was perhaps a mistake. The 209 with MX Browns would otherwise be close to perfect.
Question 2) How practical is it to remap keys in the OS and get new keycaps? It’s three keys I would stuggle with a lot # @ ”, moving those could open up more keyboard options to me.
Questions 3)
My big concerns is that I’m missing something. Is there anything else I should be looking at?
(I’ve actually considered getting two Drevo 84’s and using one for each hand, as it would still come out at less than ½ the cost of the Matias board.

Thanks for any advice and for anyone who made it through this essay!
