I'm currently using this Lenovo Thinkpad USB keyboard with my desktop system [ https://support.lenovo.com/us/en/documents/PD005137 ], which resembles the original Thinkpad keyboard.

You might find it an acceptable alternative.

This was actually the keyboard I was looking for. All I've been able to find here (UK) are the new-style chiclet ones. Looks like the ones you linked have been phased out. I can't even find them on ebay.

Having said that, the IBM one I do have is far better than I even expected. Top-notch build quality, even better than the keyboard on my Lenovo x200.
