Yeah a simple tabletop modular unit like the Moog Mother 32, Erica Synths Pico II, or Make Noise 0-COAST Semi-modular Analog Synthesizer paired up with a Keystep would be the easiest low coast journey into modular to learn how to create patches before dropping large amounts of cash. Also try out Softube a good idea paired with VCV Rack. For me, since I am not independently wealthy will probably head down that route at first.
I know guys that have 20-50k in a few Eurorack modules! And I thought that Elektron gear was expensive.
