You can start with a carbonation water machine, like a SodaStream, Soda-Club, or the previously reviewed home system, and then you can add minerals to make your own artisan mineral waters. There are several ways to calculate how much mineral you need to add. In general you start with an analysis of your tap water (often provided by your water company), then you get a list of branded mineral waters to imitate, and then use a spreadsheet to figure out how much mineral to add. Of course you can also refine your own personal mix that suits your taste, too. Finding a source for the minerals is a little bit trickier, but I suspect selling such salts will soon become a small cottage business for someone (if you know of a source let me know in the comments.) Right now check out this tutorial which tells you how:

(Has anyone tried more than one off-the-shelf home carbonation machine and would like to recommend the best one?)
