Vortex Sound Research

I am in school for electronics and want to start assembling a modular case. We have really nice soldering stations and lots of components, I can use them whenever! I'm getting a little bored of LED boards and what not. I was wondering if anyone could recommend some kits, there are some available but functionality seems limited. I've looked at MKI x Erica Synths & AI Synthesis are these any good? I wish Doepfer made kits
