If you don’t want to spend 6 hours building a keyboard that is totally understandable. Here are some keyboards at different price points. The first keyboard is a Keychron Q6, this is a great entry level keyboard that can be customized in the future if you want. There are keyboards that cost less but they aren't "hot-swappable." Being hot-swappable just means you can easily replace the switches without needing to buy other parts.
The second keyboard on my list is the DAS Keyboard 4. It has a sleek look with a really cool volume knob on the top right. A main selling point is the sleek blank keycaps. While this may not be the best bang for your buck, I chose to include it because it was the first mechanical keyboard I ever wanted.
