American Flyers, I did the "studying" over several days, several hits of the "refresh" button to keep the timer going, and finished it on the road. Print off the cert, call the FSDO, set an appointment and you're in/out in 15 minutes

Honestly I don't know if I could sit through a weekend FIRC without going crazy, but I haven't done one either so I'm just being judgemental and lazy by doing AF's course.
