The 4000 keyboards I have are pretty bad, you don't press the keys, you mash the keys.
I'm very picky about keyboards though, I need a good, sharp tactile feedback to be comfortable otherwise my hands are exhausted quickly.
I vaguely remember some A2000's with nice keybaords, but mine aren't them.
I'm currently using a PS/2 adapter with a Keytronic. For a cheap $19 keyboard they are actually really good.
I just can't use my beloved Unicomp buckling spring keyboard at home in the middle of the night or else I'd have another one of them on my Amiga
