Alright, so I have seen the Ergodex, and was interested - but with only 25 keys it didn't really seem worth the price. Now I see this:

And I am wondering - is this a replacement for damaged keys, or can someone add it to the original and end up with 50 keys? I don't need all 50, but I certainly need more than 25, and with this addition it suddenly looks like a viable and solid option.

So - what do you guys think?
