Ginger beer is good, particularly with a dash of bundy. I did the Morgans, with just a kilo of raw sugar....tasted like the stuff we used to nick from Dad's stash as kids. The Morgans does contain artificial sweeteners...I believe there are some options for all natural kits.
I have seen a kit for sarsparilla at a HBS. Apparently comes out at about 3% AV, like the GB. My guess is you'd have to pretty keen on Sars to do it.
