My Dr. helped me out financially so I only had to pay for the bloodwork, they let me be a 'case study' type so I got the medicine free. I didn't experience any detrimental side effects (I was 19 or 20 at the time).
I think I took Accutane for about 9 months. It greatly improved my skin condition after the initial increased break-out period. I have had minimal skin problems over the last decade (I'm now 29), however as of late I have been getting some of the 'nodular' type acne again. I plan on going to a dermo soon to see what is going on and to hopefully get treatment for scarring.
The most severe 'pot marks' I have are from the increased break-out period. I got a lot of deep nodular acne before things got better while on Accutane. The only other thing that was kind of a pain was the monthly blood work and pregnancy test, which I had to have and pay for every month whether or not it was even possible that I was pregnant, so that was annoying.
Overall I think it was a good choice, but the few deep scars I have bother me increasingly as I get older and I am hoping to get some effective treatments to improve my overall skin appearance.
