Like Yio, I have a homemade version---
but I started out with the stock version (for 6 years) before I felt the itch. Rack sounds OK, but I have been known to add mass (granite or maple slabs), and was not always too thrilled with the lateral stability (had a pretty heavy turntable on top). You can tighten, but mine seemed to work it's way loose (I ended up "adding" pointed feet, diagonal bracing... then I built new shelves.
