https://www.artofchording.com/ is your friend for getting started with steno. The plover discord is also a great resource. Learning steno theory can be intimidating, my recommendation is not to set a goal timeline for being “productive”. Put in a half hour a day and just take it one chord at a time.

I own several steno specific keyboards, and the Uni is my least favorite. An EcoSteno seems just to be overall better if you want a solid body keyboard, but my preference is a Georgi if you can get ahold of one.
