I think red dragon keyboards are pretty popular Herminio, at least from what I’ve seen on Amazon 
Found an Alice style keyboard similar to the BEAR… though they don’t have any PCBs in stock:
Think I am going to wait for my Moonlander to arrive and see how it goes before experimenting with others. I do like the Alice and Atreus style of keyboards so might just keep my eye on any group buys surfacing
