Almost fall into the pitfall. Have seen friends around spending 300-400$ in "custom" keyboards.

Used a couple of mechanical keyboards over time: Razer, Anne Pro II, Logitech G something, custom made, Asus Rog TKL etc. Well, used those for fun with PC but my major workhorse has always been Mac setup: MacBook + Monitor + Magic Keyboard/Trackpad, and productivity has always been there with this setup.

Although I spent some time with Mechanical keyboards, still Magic Keyboard TKL scores the highest, in terms of productivity, stability, comfort.

You can have fun w/mech keyboards, but I'd rather spend my time onto something that actually matters. Go with simplicity without overthinking and wasting time.
