Assorted Road cases. Many have airline approved "draw locks." Some are solid aluminum cases. There are several brands but most are Viking. All have been used for photo equipment in various sizes. Most have the airline "draw locks" like you see on aircraft, which makes them great and secure for shipping. None were specific for musical consoles. Almost all of them need to be cleaned out and repartitioned for your personal needs. The foam inside is sticky and disintegrating; however we cleaned a couple out and it was easy. The $20 is NOT for the group. They are various prices but do start at $20. The new photos with the "Xs" have been sold.
