Thx all for your help. I finally I choose the Cherry G80-3000 (spanish layout) because:
- Filco otaku (ver expensive, blank keys, no spanish layout)
- Unicomp EnduraPro (very big, horrible sound, horrible colors, expensive)
- HHK (no spanish layout, blank keys, very very expensive)
- RealForce (no spanish layout, blank keys, very very expensive)
- IBM Model M (without windows keys [basic for my mac, i use much command key], horrible sound)
The cherry g80-3000 great sound, spanish layout, not expensive, with windows keys and confortable for coding for me, the only downside is that it is big and don't have the brown switches (only black swithes in spain G80-3000LPCES-2). I will try change my height (in the chair) and move my table for to make a ergonomic desktop with the cherry (avoid problems like carpal tunnel syndrome, tendinitis,...)
Thx for your help!
