If you're in the market for a one-man-band style keyboard, this model *$699* seems to be the "hot one." Compares favorably with $2000+ competitors.

Few American dealers carry it. Don't know why. Supplies could be short, due to COVID-19.

Of course, the budget mode for digital music production is to get a decent MIDI controller that will interface with your computer (desktop or laptop).
One of the better configurations is the Novation Impulse 61 (matching the number of keys on the Medeli) $399

It has a lot of features for controlling a digital audio workstation (DAW), including transport controls.
Another option is to get an 88 key, hammer action MIDI controller to drive your DAW. That's one way to get "classical" feel & modern tones on a budget.

What the extra $300 for the Medeli delivers is the internal computer sound engine, stereo amp & speakers, and super customizable controls (and colored lamps). . . .and the touch screen system that makes it intuitive to control.

ALTERNATIVES
The cheapest are the Casio Workstation Series (WK6600, WK7600, and earlier)... $450 and down.

It gives you a baseline to compare others.
The sad truth is that any computerized keyboard you buy goes obsolete within 6 months, as the technology advances. So many musicians are just buying MIDI controllers, and using their computers and software updates to keep current.
