i wanted some information on a recommended keyboard model to start learning the piano (I don't have enough space at home for an actual piano right now). I would like something that is inexpensive for a beginner, but also durable and won't quickly become obsolete.
_no line outputs for external mixers/amps (you have to make do with the stereo headphone jack output, which is sufficient if needed)
But:
_weighted keyboard is more than decent and pleasant
_grand piano sound (clearly what matters most, especially if that's all you're interested in) is excellent
_"pop/bright" piano sound is excellent; strings are also excellent, especially useful for layering them with the piano sound. The other sounds, besides being few, are not very interesting (organ 1 and 2, electric piano 1 and 2, vibraphone, clavichord).
In 2014 I bought a Kawai MP11 for 1880 euros, in installments. I have played about 3500 hours on it; the ivory touch effect disappeared after two months, and now the keys have some problems, meaning they don't descend well, at least some of them, but otherwise it has lasted quite well, meaning it has survived with dignity, good sound, etc. The keys are a bit light compared to a piano, legato is a problem, but when you move to a real piano, I am talking about an upright piano, legato, trills and tremolos are a marvel; that is, a good instrument for practicing, even without disturbing anyone
