Hey there!
I trained at a Private Training Establishment back in 2004, who are now booming with lots of International Students.
If you want details, PM me. I found them excellent (not that I had a lot to compare it to then, but I have a bit more now!) they've been operating for years, more one-on-one than your average aero club (in this region anyway).
I can highly recommend them, and currrent costs are AROUND $140 an hour dual for a C152.
I'm not sure about other regions, but we don't generally do mountain flying as part of the syllabus for PPL, but this can be incorporated into CPL hour-building if thought necessary in the individuals circumstances.
Tis a great place to learn to fly! (And, no... I don't work there or have any association with them!
)
Hope this helps!
