LOOKING FOR: Sugar free Low(or no) cal syrup recipes

DaSavedSinner

We like soda but prefer to make it ourselves using a home made water carbonation kit. We have used sugar free drink mix (ie, koolaid) but the cost is not effective....We are looking for one of a few options, first off we need a no/low cal sweetener that is cheap without any fillers, such as liquid sucralose like ezsweetz (like it but have none right now), then the next step is our flavor source. We are about to tr using fresh and frozen fruit to come up with some trial runs but we also would like to find a ratio of water/sweetener to flavor extracts like you would buy in the baking area of a store. This is our main goal, to find a way to use extracts with water and sweetener to make a simple (sweetened just add extract) or complete (just add to carbonated water). I know this is kind of jumbled but I have no clue where to start and I don't want to waste alot of cash trying ideas....Does anyone have any ideas or recipes to help with this?
