The best keypads were the old, legacy 12Cs. The next best were the 30th Anniv editions that came out in 2011. But those 30th Anniv models are now selling for $300! And though the keypads were great, they just didn’t hold up like the legacy 12Cs. But you can take one of these current 12Cs and if you’re even a little handy, you can modify it to create a 12C with a fantastic keyboard feel and no non functioning keys. Look for my 4 Star review on Amazon dated 9.18.20 (https://amzn.to/334b0El) and it will walk you thru the simple process. Buy a cheap used one in good condition that uses CR2032 batteries, maybe its a return “bcz the keys don’t work,” and make yourself a $300 30th Anniv/ fast Legacy edition. I have the full description of what to do and pix with it.
