I need your thoughts and suggestions about buying:

JUNO DS-61 (with 61 keys) that has a great amount of famous sounds (1200), many effects, and layering up to multiple instruments for the price of synth keyboard, not weighted.

or

88 fully weighted keys for the price of not many instruments (20)

I've been producing music for couple fo years, but also want to play piano on its own. Would you say that synth keys are bad enough to buy digital piano instead? Also i need those sounds, FL doesn't have amazing library in my opinion.

​

If you want to suggest me different products my budget is up to 750$
I would highly appreciate any help as I'm lost and confused as hell.
