I have a Soyajoy machine. Its very quick to use, put soaked soybeans in basket, add water up to the line, turn on, 15 minutes later soy milk. I add 1/2T vanilla and 3T sugar.
It doesn't taste like Silk, its more of an acquired taste at best.
google making soy milk, you can make it without a machine first and see if you like the taste.
Its good for smoothies, not so good with cereal and such.
