Hour or two. Went up with and instructor and did PPL stuff, stalls, steep turns etc and then a few landings. Whatever pace you fell comfortable with then that's the best. If you want another few hours with an instructor than so be it. Know the POH and the big differences (fuel pump v's gravity feed). Other than that it's just another SEL plane.
I flew Cessna's (152 mostly) for the PPL, and Pipers (Warrior and Archer) since then. Prefer the Piper, something about looking out and seeing the wing below you.....!!!
