That's great that you found the source, I was about to call BS on NMI as the 2019's on dealer lots still have plastic tanks, but they beat me to it and corrected themselves, glad to see that. Regarding Fisheries Supply, I just added both tanks to my cart and it's showing "free shipping" plus $30 oversize charge. Maybe the free shipping doesn't apply based on your location in Canada? Or you can also pick up from Seattle for $0. But what's your time, gas, and ferry cost? $212 shipping doesn't sound too bad if these are actually in stock as the website indicates. And designed specifically for a CD22!
