To clarify what I said in the video, the company that installed it didn't suck. They just took way too long and cost too much. The first company I tried to have it installed by was the one that sucked. They held my guitar for a week, didn't touch it and then got an attitude with me for saying I wanted it back.
To the hundreds of people who have asked how to buy it: there's an interesting little website out there called Google. The first search result for "sustainiac" is the official website. I'll let you figure it out from there.
