Hi Jazzer83 - 30 year glider (and ex-PPL) pilot from downunder here. If you want to fly because you love being airborne, and you have a sense of adventure, then gliding is definitely a lot more interesting that PPL flying. Possibly not cheaper initially i.e. before you go solo but definitely much cheaper afterwards. The downside is you can't really just rock up to the airfield and go flying for an hour - it's usually an all-day commitment, although that would depend on the club. Good luck!
