As you can see, the Klean Kanteen Classic is among the best ones, and not significantly more expensive than another, and also widely available.
Otherwise, Pura Stainless and Ecotanka bottles are great aswell, and among the pricier, Nalgene Guyot Designs and Tatonka bottles; I haven't tested any Tatonka bottle, but I know they make good stuff, and I'm certain they're >0.4mm thick, but still, I need to actually check that.
If you now of any other brand making steel bottles, I'm interested by the way.
