Nothing else has the Model F mechanism. The Model M has a similar but not as good mechanism. If your question is really "where can I buy a good ergonomic mechanical keyboard with high quality clicky keyswitches", the answers are myriad. Ergodox and variants are columnar and split. The Moonlander is columnar and split. X-Bows are columnar and angled but not split. All of these can be bought with blue and/or clear and/or green series switches.
