Just to throw in a tangential idea:
Some people want the "weighted key" "piano action" style keyboard because they want to have the play-ability of a piano which cannot be obtained with synth style keybeds or anything else.
Plus, people want a range of features: realistic piano sounds, organ sounds, portability, user-friendliness, easy set-up, etc.
Plus, everyone wants a good price.
A challenge is that to get all three - piano feel, features / sound, and price, you really have to search or compromise.
One option to consider is to buy a keyboard you like, but plug it in, by midi, to something else for sounds and effects.
You can get a modest-price keybed you like, and stick with it forever. Or, if it dies, replace it, but retain and upgrade the rest of the set-up.
You can plug a keyboard into a sound module and run that signal out to an amp.
Or, you plug your favorite keyboard into a laptop via an "audio interface," and out to amp.
This way, you always have the keybed you like and are familiar with, without having to buy all of the function in one bundle - keybed, sounds, features. Plus, you are set up to record in DAW.
As far as I know, no one makes an 88-key keybed with no features except sustain pedal-in-in and midi-out and maybe volume on the unit (so you would not have to clik in laptop to change volume). But this would be cool.
You spend $500 maybe for an awesome keybed, then just run it however you want, otherwise. Who knows - maybe someone could make an awesome keybed for $200.
I get this idea from synths. Almost any keyboard, with lousy or great synth feel, has midi out. these are "controllers." They merely send out the key press signal. They start at $200 and go up. However, I have never heard of one claiming to have the same feel / action as a piano.
The Yamaha p45 is around $500, but it i snot just the keybed; it includes the piano sounds onboard, as well as other sounds. My idea is that you could merely shop for the key bed, and get the sounds elsewhere.
