I suspect you‘d get more for less with a standalone synth like the Microbrute or a used Analog Four, and you could always get something semi-modular, again Microbrute or any of the Behringer Clones if you enjoy patching.
Atleast that‘s my reply if all your looking for is a little flavor for your productions.

Don‘t underestimate the rabbit hole and price of modular.

But I‘m sure someone more experienced will chime in soon!

All the bestest
