I've had a Moonlander and a few other ergo mechanical keyboards. I never liked them and they didn't seem to help my forearm pain as much as I hoped. After a lot of time and well over $1,000, the 2 things that solved it for me were: (1) get a soft, membrane-style wireless keyboard and put it in my lap when I type. I've found the Logitech MX Keys to be the most comfortable. (2) Use compression arm bands when typing. They're cheap. All-in, you're looking at about $150 for a high-comfort solution. YMMV.
