...But first I'll be smart and make sure I can afford it too.
Sensible guy - if you are doing this for fun, great, but make sure you can finish it because getting half way through and having to stop will be torture.
I'm about a third of the way through my PPL - doing it for fun with no intentions of becoming a commercial pilot. Only comment I'd make is that $5-$6k seems a bit low for me these days. My experience would suggest doubling that unless its being subsidized somehow.
For what its worth, my flying lessons are currently the highlight of my week.
