+1 for starting with Tip Top HEK. I built many variations on ModularGrid, watched videos, and honed in exactly on what I wanted.
I specifically also chose a Disting MK4 (bang for buck) and Expert Sleepers ES-8 based on a really cool video by Loopop. ES-8 allows VCV rack to bridge the gap from my computer to the hardware setup and back due to the DC coupled i/o. I will be able to use this module for the foreseeable future.
