Lunch Boxes

Just in case anyone looks at that this anymore besides me :) ... so we all know plastics with BPA are bad, but have you heard of stainless steel leeching too? I got one of those water bottles & my water tasted metallic, so gross. I also read something by Raymond Francis (Never Be Sick Again & CEO of Beyond Health) who says that toxins do leech into whatever the container is holding. I want a better option for my boys' lunch boxes & this website is so appealing...but are they right? Or is Raymond right? There are also these Bento boxes, but are there are other toxins we should be worried about in plastics besides BPA?
