I purchased a soda stream machine about a month ago it pretty cool You can carbonate a bottle of water quite easily and they sell syrups to make flavored soda Cola, Orange, Dr Pepper style, Cream and many other flavors and a few diet flavors, their syrups are the old style pure cane sugar syrups. 35 calories per 8 ounces vs 110-120 per 8 ounces of the modern sodas with corn syrup, and they taste pretty good, I like the Ginger Ale, for people who like mixed drinks they make a tonic mix.
