Curtis or Johnston Aviation
Yeah, I'll put a vote in for Curtis as well. I did mine there. All your training is done with experienced Grade 1s (no mutual). The other student on my rating course got a job there (I had one lined up elsewhere).
Even if you don't get a job there, the tail-dragger keeps you on your toes, and moving to a C-150 or something makes things pretty easy (type knowledge aside).
Johnston Aviation is the other one that's pretty well reputed. I finished off my PPL with them, and did my CPL hour building up there. Beautiful part of the world to fly.
