Favorite keyboard is the 3000D keyboard. Best feel, great life. There is a difference between the various Amiga models, I lined them all up to confirm and to my fingers the 3000D is the best. Tried multiple 3000D keyboards to confirm quality and yep, they are all wonderful. 2000D and 4000D keyboard is a bit mashy and tough.
If you wanted to go the clicky route, NMB and other similar PC style keyboards are fine.
Using a Microsoft Ergonomic 4000 now, and it is ok. Nothing compared to the Amiga 3000D
