We have a soda club machine. It takes regular water and turns it into sparkling water. Then you can throw in a lime or lemon slice to serve as mineral water or you can use a syrup (which the company sells) to make soda. We also buy bottles of syrup for around $3 at our local restaurant supply store. It was pricey to purchase the machine (around $100 I think), but it was soooo worth every penney. We use it constantly and never pay for soda or mineral water anymore. Here's the site so that you can check it out for yourself.
Mix club soda with water ;-) Just experiment until you get the 'sparkle' you like. I happen to like half and half and sometimes add flavoring ;-)
