On Flint Craigslist, two for $2000, or twice as much as they are probably worth. Found a closed sale on eBay for around $500 for one.
Couple of single ski things on this site.
The Snow Hawk is pretty sweet. Not a conversion but probably wish it was with the $ sixteen thousand dollar price tag! I must be out of touch with price points on toys.
