Found these on Amazon and mixing XTol just became easier. They are ABN 5-liter "paint mixing pitchers" and a 3-pack is $32.95. They are quite heavy duty, marked out in US and Metric measurements and have a nice wide handle for gripping and a good pouring spout as well. Not going to post a link, because it will just get taken down. But do a search by ABL 5-liter and it will come up.
