Wide 20" rim/wheel (42mm or wider) KH, Impact, Nimbus, Mad4one [North America/Australia]

Hello,

I am looking for a wide 20" rim, or alternatively a 20" wheel.

Any of these:
Impact 20" rim - 47mm wide
Kris Holm 20" rim - 47mm wide
Mad4One 20" rim - 46mm wide
Nimbus Dominator 2 20" rim - 42mm wide

I’m located in Canada at the moment, so I would rather buy from someone in North America, or alternatively in Australia sometime in May or later.

EDIT: I am not looking for a 19" trials rim, I am looking for an actual 20" rim.
