My advice for anyone that wants to get their pilot license for fun is as follows:
Don't look at the cost of getting your license as money that you have to spend in order to start having fun. It is part of the journey, and flying is fun weather you have a flight instructor sitting next to you, or if you are on your own.
Figure out if you can afford it. For your training count on about 1 hour of flight per lesson, and 2 hours of instructior time per lesson. You want to fly at least 2 times per month while you are training, otherwise you will get too rusty between lessons and forget a lot. The more often you can afford to fly, the easier it will be for you, and the less hours you will need to complete your training.
Toward the end of your training you will spend money quicker because you need to complete a few cross countries which will run you probably 3 hours per flight, then you have to pay for your testing as well.
Sign yourself up for a ground school so you can learn as much as you can ahead of time. It is much cheaper to learn a lot of the things you need to learn in a classroom setting, than one on one with an instructor at $30+ an hour. Do your reading ahead of time, and be prepared for your lesson.
Lots of good reading here for free. Start with the airplane flying handbook, then read the Aeronautical information manual. Those 2 books contain almost all of the information you need to know to get your license.
