If I tell my tale that may help you decide.
I have only been playing keyboards for about three years after many, many years of guitar playing (6 string and bass) but age and in my case arthritis in my hands with it worst in my left makes fretting difficult especially for solo riffs and instrumental pieces so I thought that I would give keyboards a try.
I bought a fairly low cost one and started playing, I progressed pretty well but then I grew to hate the keyboard, its action was just OK. The problem was that the menu system was dire, with button after button press being required to just do a simple task and whilst I had never liked the tonal qualities of the keyboard the lack of tonal quality was really starting to bug me but the keyboard was what it was a budget beginner board.
I do not have a dedicated room to play in, just a corner of my Dining Room so mostly I use headphones so I can rule out rubbish speakers inbuilt in the keyboard as being the source of the poor sound, playing through the inbuilt speakers was never a pleasurable experience and that is still the case with most budget models.
I sold the keyboard in question and bought my Korg PA700 which is light years ahead in terms of quality of build and sound but it is 4x the price.
The keyboard that was the source of my annoyance, a Yamaha PSR E363.
You have duly been advised what not to buy.
Finally please remember what Ray and myself have advised, these are keyboards, they are not pianos, yes these keyboards have piano sounds but the whole process of learning to be a pianist is totally different than that of being a keyboardist.
