Thats what Im trying to find, and I cant seem to find a canadian dealer, or even a dealer that ships here

I've got a couple of more placed to ask, but does anyone know where to find this thing, or something similar?

Bump. I can't seem to find any locally or on the net (that will ship to Canada anyways).

Is there anything similar?
