AF's FIRC is easy though, and just take a few days or over a week, leave the screen open while you go do other things, and it'll still count the time. Just be sure to actually read through the section at least once. It's 100 minutes of studey per chapter.
Not to mention, LIFETIME fee of $125(I think it's still that) I'm doing my renewal right now, keep plugging at it every once in awhile, I'll get the paperwork ready this week to take to the FSDO, just have Chapter 8 to finish.
Now, in your case, just do the CFI-I. It's the easiest check-ride you'll ever take!
