Very interesting system. I don't think that the material used for the wand would really matter as all its function would be to get the jets up in the air. Could you make your own system for cheaper, I would think so but you would spent the entire winter trying to find the right apeture size, air/water mix etc. Snow making is very basic, but the 'recipe' is where the true craft lies. There was a thread awhile back about these two that made there own ski resort, and snow making was a big part of it.
