alternative to plastic bottles

If you read my earlier post about the dangers of plastics and now you want to switch from those plastic baby bottles or water bottles, check out this site that I just found out about: http://www.glassforhealth.com/

I'm still on the lookout for stainless steel water bottles THAT DON'T LEAK for my kids to take to school - I found some aluminum ones but I'm not crazy about aluminum either - though I'm not sure if it's just founds heated in alumimum that cause problems or if water stored in them is bad too. Anyone know?
