Unfortuantely, yes. An average price is around $100. But, it may be more helpful in the end. Say a store sells pre-mixed water for 70 cents a gallon. You buy what you need, and go home. Come back when you need more, go home, etc etc. Between the gas prices, water, and the top-offs you need, it will all add up to be more than the diffuser eventually. Plus, you would always have clean water for you and your family. :)
You could try finding a used one on Craigslist.
