I really love the Sinusoda cans—you can continuously expand your existing Sinusoda case as you build your dream machine! Right now, I have this attached to a Sinusoda Six Pack. They're made of plastic, which might be a downside for live performance, especially if you're using a large system. However, for just a can or two, they're great for traveling and perfectly suited for home use as well. A bonus is that all the cans come with accessories that let you attach them to your existing Sinusoda setup.
