I would love to have a new Vitamix with a stainless steel cannister. I avoid plastic touching my food. I posted on Vitamix's webpage asking them to do that and people keep liking and adding their comments. Turns out someone has a petition at http://www.change.org/petitions/vita-mix-please-bring-back-the-stainless-steel-pitcher
for the very same purpose. Please sign the petition if you would like this as well.
And why would you want a stainless steel cannister?
"Almost all commercially available plastic products we sampled—independent of the type of resin, product, or retail source—leached chemicals having reliably detectable EA, including those advertised as BPA free. In some cases, BPA-free products released chemicals having more EA than did BPA-containing products." http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3222987/
