Padded DJ Controller Case for Hercules DJ Inpulse 500, DDJ REV1, NI Traktor Kontrol S4 MK3, DDJ SR DDJ SR2, Numark PLATINUM FX, DDJ RR, Akai MPK225, 23.5 x 14 x 3 Inch, Black

I ordered a couple from Amazon to try out, and this is the one I'm keeping. It's a little overkill, but the padding is substantial to protect to corners, it doesn't feel like the pegs will poke through, there's a ton of pockets, and (most importantly) the board is easy to get in and out. I got it on sale for $27. https://a.co/d/00JNio1X
