I’ve decided copy @unik and build a tiny board with fat off-road wheels, but finding a Jet Spud has been difficult since they discontinued the line. As luck would have it, I live in one of the remotest outpost of the empire (ie. I live in Australia), and sometimes things move slowly. Searching locally, I found possibly the last stock of Jet Spuds that are commercially available.
I know the Spuds are popular, so if you’re looking for one you might want to try here … http://www.extremeskates.com.au/brands/jet/jet-spud-29
I would suspect that supplies are limited, and I don’t know if they ship internationally.
