This is good advice. Whatever you do, don't get in to eurorack, because that way lies ruin. What makes it worse is that we seem to be entering the second golden age of synthesisers. There is some incredible innovation out there from companies both small and large and even the analogue revival synths seem great - see the Korg Minilogue, all the reissued Roland System 500 stuff by Malekko. I've just seen the Arturia Matrixbrute and I am desperately trying to wipe it from my mind.
...if in doubt consult your dealer.
