Favorite large water bottle/jug?

I'm looking for a stainless steel one that will keep ice for a while. I have a smaller bottle that I take with me everywhere, but I'm REALLY really picky when it comes to my water and ice. I'm a babysitter for 2 different families and I can't drink the water. I hate the taste of it. So I want a larger jug that I can fill up at home with my ice and water, and then use that to fill up my smaller bottle while I'm at their houses.

My smaller bottle is 20 or 24 oz and I go through about 3-4 bottles while I'm at work, so a 60-80 oz would be preferable.
