I hear all that @Lugia, but as an acid fanatic I'll chime in to say that modular does open up some really interesting room to explore the acid sound, and folks are looking at the challenge you've raised re: the sequencer thoughtfully, for example the m303 has a Slide input that aims to mimic the TB-303 sound. It never hurts to go the VST route (and certainly helps the budget) but as someone who started his Eurorack journey to make ambient/drone/noise I couldn't resist making squelches once I got a rack in my hands... there's something there there.
