I researched this one (almost embarassed to say) for almost three seasons. I tried everybody from Camoplast to the real small companies to the Chinese rubber companies. The answer is no, not without a minimum investment of at least $12,000. I was working with one small company in NY who promised the world, but ended up ditching me 3 days before HayDays '07. And the three chinese companies I worked with eventually made it clear that I had no market protection from them whatsoever, and that they may go after it themselves if they saw profitiblity. And bigger companies (USA) were happy to give exclusivity, but wanted $70,000ish to start. There is just no existing track anywhere that would be a direct fit or even close. I even went so far as to try to license Yamaha's molds and drums to make a stock length track with taller paddles...denied, but I understand their postition.
Camoplast has been unreal in their cooperation and support, (Bruce has been a great educator to me, and even had a track overnighted to me to mock up for HayDays when I told him of my plight) but the bottom line is that it takes a fairly enormous amount of capital and resources to make a new design (length, width, pattern, etc) from scratch. SO, we have adapted one of their existing tracks.... which you will see soon.
