yeah. i'm into classical piano. Unfortunately due to my tertiery studies i cant seem to "afford" a full upright classical piano for the rented apartment. Hence, i considered digital piano.
If you're into classical piano, you might wanna consider a conventional upright piano rather than a digital piano, unless syou can find a cheap digital piano with features useful for your classical piano skills/techniques likes half-pedalling, key-touch sound sensitivitiy (not sure what's that called, it's not touch sensitivity... you only find these in high end digital piano). But then, if you don't mind these features and prefer the digital, then go ahead and try out each brand and models.
I suggest you to try out the different models than plainly listening to opinions. Each person will have their own views and brand suggestion. Use other's views and suggestions as a reference and then try it out yourself. The sound, touch and feeling from each brand and model is different.
Personally, I would suggest you to try out the latest Roland model with PHA-II keys, but it's not cheap for a Roland.
For closeness to the conventional piano, my personal view would be the Kawaii brand, to me, they have the closest "touch" feel of the conventional piano, with the sticky keys feeling.
If you want space and easy to move around, then I suggest you get a portable or sometimes known as STAGE Pianos (which some called Keyboard with Weighted Keys). Basically, keyboard/digital piano, they're the same thing, just different naming, a keyboard is simply a portable digital piano and they come in weighted keys or non-weighted keys. As technolgy advanced, they separate each into different categories, like Arrangers, Stage Pianos, Workstations, etc. It's simply keyboards with different features/functions, while keyboards are simply portable digital piano or vice versa, piano are keyboard instruments.
For Portable Digital Piano / Stage Piano, Roland's one will cost a bomb. You can try Yamaha one's, it's around 3K++ if I'm not wrong and it's quite good too.
Casio will come cheaper but I wouldn't really recommendeds it, why not spend extra little to get a better ones, you're going to use it for long time right?
Anyway, you should try out yourself whether these are good or not, it's just my personal opinions and suggestions.
Good Luck and All The Best!
