Where can I find a wasabi plant?

Where can I find a wasabi plant?

I realize that my zone 5 weather is not exactly a prime climate for wasabi, but I would really like to try growing it. I've googled for pages and pages and the only place I can find that sells the plant is a place located in Seattle. Does anyone happen to know of a place (much) closer to New England for getting a wasabi start?
