Now I obtained a blue Alps keyboard. The keyboard itself is not that good, it's Chicony KB-5162. And I need a keyboard with Windows keys anyway. My choices are:
1. Dell AT-101W. Most obvious choice, but this keyboard is way too big for me. Focus FK-2001 is the same category.
2. Custom keyboard. I was able to find only 60% sets (PCB + plate) easily available. Even then, I don't fully understand what stabilizers do I need for such a build. The keycap availability may also be a problem. And I don't really like 60%. Ah, there is also some 75% orthogonal set, but I'm not into this kind of experimentation at this point.
3. KBParadise V60. Same as #2, but without stabilizer/keycap concerns.
4. Filco Zero. This would be perfect. 80% is my favorite size. I just don't know how easy it would be to obtain it.
5. Maybe some Matias keyboard? They look kinda ugly in my opinion. Are Matias switches perfectly interchangeable with Alps?
6. After some additional research I found that KBParadise V80 comes with Matias switches. This would be ideal. Again, can I just replace Matias with Alps?
