Apparently, that Cherry A2000 keyboard is fairly rare. I think most A2000 keyboards (including mine) are the NMB version. My favourite Amiga keyboard is the A1000, made by Cherry.
You can see the different Amiga keyboard types in this EAB thread.
$1200??? What? Holy cow. I have all the rest of the Amiga 2000 to go with it too, 5MB of RAM, deinterlacer card, dual floppies (now we're cookin'!), Hardframe/2000 SCSI HBA, 8088 XT PC bridge card. If all the rest of it didn't still work I'd let that KB go for anything remotely like that kind of money. Perhaps it's time to look at parting the old girl out.
As far as I know the only issue is some wear on the left Amiga key since it is printed instead of double-shot like the rest of the keyboard.
Interesting link - thanks.
