Years ago a bought a product called Almond Cow. It is not cheap, but it paid for itself in a year. We make almond milk with almonds and water, period. Takes about 3 minutes to make. It is great! Have done so with oats, also, but need to shake it before drinking because of the gelatinous quality of the oats.

If I am buying non dairy I buy Trader Joe’s soy drink, it is soy and water, or Westsoy brand soy milk, again it is soy and water. I buy the original because i don’t want any additives or sweeting in mine.
