I went the DIY route due to budget constraints because I wanted to invest more in tech. Even if I used simple products like some pieces of wool, paint and nails, my standing desk for music production ended up excellent.
Regarding tech, I chose the Native Instruments Komplete Kontrol M32 Keyboard and a good computer and mic to have a good product. The keyboard is under 200, and for what it's offering, it's more than perfect. You can see more details about it or other products in this article.
