New member here, trying to decide if Insight is worth it

Obviously, the Insight is worth it to the owners here, but I'm trying to decide if it will be worth it to me in my own personal circumstances.

I currently drive a Honda Del Sol, which is enjoyable especially during Spring and Fall, but I really want better gas mileage than the low 30's I'm getting with it. It cost me about 5 grand, but it's paid in full, and has so far not had any major problems at 140k miles. I'm currently a student with a very small commute, but for those roadtrips and trips home, it would be handy. I'm also moving to Houston for the summer where I'll have at least a 25 mile commute to work. The increased mileage of an Insight would be extra nice here.

I considered purchasing a used Insight until I read the forums here for a week or two. The general direction I was getting from owners was to buy new to get the warranty and possibly a tax break. I even called the dealer and found that I could have new one in two weeks if I pay a deposit. However, purchasing an Insight would require me taking out a loan, and I will be paying it at least until April 2007. Plus, from what I've read here, there won't be a tax credit for the 2006 Insight, and may or may not get a tax deduction.

So, while this will be a personal decision, I wouldn't mind some input from experienced Insight drivers (and possibly some individuals older and wiser than me). Is the better gas mileage worth getting into a car loan, and will the savings really pay for themselves in my case?
