It depends how tight your budget really is and what kind of flying you anticipate doing. I started to do a tailwheel conversion in a Chipmunk, but couldn't afford to keep flying it. So, I have now bought a share in a tailwheel microlight. I didn't learn to fly to get across to France and Belgium every other weekend - I learned to feel the wind in my face, get a new view on the world and just have fun. If I fancy doing more than 50 kt and having little luxuries like doors, I can always hire something for a few hours.
