Most Amiga keyboards in general have the cheaper rubber dome keys. Compared to all of them, the Amiga 3000 keyboard is the best looking one in my opinion.
But if you have to settle for an Amiga 2000 keyboard, keep your eyes out for the model that has the mechanical keys. They are built much better and the keypress has a more distinct/solid feel compared to the cheaper rubber dome type. Many people notice it looks slightly different but don't realize it is rarer and built with a higher quality.
