What a neat comparison! I've just recently been looking into keyboards myself, as I needed something for my A2000, and even my A1000 keyboard has been having some issues with keys sticking.
I thought it would be an expensive hassle to go out of my way to find an A2000 keyboard with mechanical switches, and the info in this thread tells me I'm probably right, especially seeing how Amiga keyboards are usually priced on eBay. Instead, I got this:
This is a custom WASD V3 keyboard with Cherry MX Blue switches (I love the feel of Blue for typing), but on their website they actually provide the option of making the OS keys Amiga keys! You can technically upload a fully-custom keycap print, but that would be a ton of work, so it was amazing that they offered the Amiga keys. In the order comments I asked them to print those keys red, and they obliged.
I also had the option of making some of the keycaps gray like the Amiga keyboards (and many other 80s keyboards), but I had to go with the more minimalist look of all white. It's really the Amiga keys that makes it feel right at home, anyway.
For an adapter, I use the Lyra 3
from Individual Computers. The adapter has some really smart features such as remapping keys, mapping useful keys to ones that don't appear on Amiga (eg. Home/End map to Shift+Left/Right or Alt+Left/Right, depending on your setting), and even the "stealth" protocol that lets you use MMKeyboard
to map OS commands to your keys. Important to note is that the WASD V3 no longer supports the PS/2 protocol needed for this adapter, but you can downgrade the firmware to V2.5 which does support it. That's another big reason I went with this keyboard, as it's quite difficult to find modern mechanical keyboards that still support PS/2.
Not to derail the thread from the topic of actual A2000 keyboards, but I wanted to share this as a solid alternative.
