I’ve got a JSAUX modcase, and it’s been great for deck portability. The case that came with the deck is great for protection, but too big to fit easily in my bag I take to work. The modcase provides enough protection to put the deck in a bag, and has made it a lot easier to take with me. dBrand did this first with the Killswitch case, but it was a bit more expensive than I was willing to pay. I think some other brands have since made their own versions of it, but I don’t have any experience with those.
