Is Buying a Hybrid Car worth the money?

Gas is getting so expensive is buying a hybrid car worth the extra money? You expect to pay anywhere between $3000 to $7000 more for a hybrid so is it really worth it in the long run? I mean $7000 can buy alot of gas. According to a survey hybrids only account for less than 3% of the U.S. car market. However, you do get a tax credit when buying a hybrid which can help the cost some, but not all. In a study from Edmonds.com it would take 12.5 years to pay off the difference in gas on an Honda Accord Hybrid if you drove it 15,000 miles a year.
