However, I have noticed that the only people who look at a product like Chompi and think "overpriced" are people who have never built and shipped a hardware device. Perhaps you'll be the one to prove me wrong.
I'm not saying that Chompi wasn't expensive, or that you couldn't get a mass-produced device like a Roland SP-404 for less on Reverb. I am saying that that is not a fair comparison, however.
