Hi!
I'm from Spain too! I've recently bought my first mechanical keyboard too, i wanted Cherry MX Blue with spanish layout and i bought a Razer Blackwidow Ultimate.
If you are looking for tenkeyless, your two only options, as fas as i know are:
The Cooler Master and Zalman ZM-K500, the second one is available through pccomponentes.com BUT is uses bad switches (some kind of low grade cherry copy).
Other options:
You can get a KBT Pure Pro with Spanish layout, which despite being a 60%, have the the arrow keys more or less on it's place.
Also, i think that might be possible (but very difficult) to find a IBM spacesaver with spanish layout.
As a last option, you have a couple of strange tiny spanish layout with arrows mechanical keyboards:
CHERRY G84-4100
and
CHERRY G84-5200
but both use Cherry ML instead of Cherry MX
So, if i were you i would search for a Cooler Master, maybe online or second hand, and as a second option go for the KBT Pure pro (is a nice board).
My next board will be using ANSI layout as i want to learn it so i can have more keyboard options in the future.
See ya!
