After doing some research, I have decided to build my first modular rack and modules from scratch. I am planning on building all of these modules based on the schematics provided by Noise Reap. I have plenty of experience soldering, analyzing and troubleshooting circuits, so no need to worry about that. I'm currently studying electrical engineering and have plenty of desktop/hardware synths (LXR Drumsynth, Roland Juno-106, ...) and am excited about getting into modular synthesis. I understand the two different schools of thought (east and west), and I think I could start out with the east-coast subtractive style. I started out with a couple modules, or at least the ones I thought covered the basics. Let me know if this rack works or if you have other suggestions, thanks!
