First get a little more experience, especially of different aircraft and what they can achieve.
Agree with this. Wait a year or two, to see what kind of flying you *really* do. Then you know what kind of aircraft you need.
In addition to that, don't try to find an aircraft that fulfills 100% of your requirements. You'll probably end up flying with empty seats 90% of the time. Find an aircraft that fulfills maybe 80% of your requirements, and rent (or fly commercially) for those flights that can't be done in your own aircraft.
