Home carbonation systems have become trendy in recent months. Maybe this has something to do with the economy. Carbonation systems can be purchased for a little over $100. Some would say that after purchasing such system, you would save hundreds on soda and/or other carbonated drinks in the years to come.

I particularly like the Penguin Carbonation System $199 (including starter kit ingredients) from Soda Stream. This system has a very nice, industrial look and feel to it.
