From a performance point would a 250 Comanche fit your needs. Goes fast with speed mods goes even faster. I don't think there is any single today that can beat it and it has range trouble is a bit old. Believe there was a South African company making a composite copy don't know if still around.
From what I've heard the Comanche is still a very competitive aircraft by todays standards. Like any second hand aircraft there can be higher than normal expenses to start with depending on how well the previous owner maintained it.
However the the is the Raven, it has pretty impressive specs
