I'll add that there is a difference in quality between Klean Kanteen and whatever cheap ones you find out there at Walmart or whatever store. I have a couple Sub-zero ones that I use for work and they are pretty decent and not total cheapos, but the KK are worth the extra money if you have it. The brushed stainless steel is what I would buy (I have a 16 oz one) because the paint won't come off and they recommend handwashing the painted ones which is a real turnoff for me because I like being able to throw them in the dishwasher. The brushed stainless steel is dishwasher safe.
