Very kewl! I've always wanted to get one (or two, lol) of these for my collection. Would be a great way to store some of my props I wonder if they'll ship to Canada, though.
FYI, the 2-drawer one you linked to is close, but not entirely accurate to the screen-used carts. Those were the 3-drawer configuration (it's the Organizer B33 model), which appear to be available for $450 USD.
Would be nice to get one of the Stile Noelt ones, too. There's only one on eBay, but is a 6-drawer model. Yours is off to a good start, I'd say! Looking forward to seeing you detail it
