If you want only a new plane,then a LSA might cost $100 K or more like $130K.
But a good Cub is under $40K, a Champ probably under $30K and is is both a real airplane,( by that I mean not a version of a hang glider,) and is also legal as an LSA as are a few others.
If $30K or $40K is too expensive, well ultralights are much cheaper, and have their own attractions, even if it is not something you are likely to fly very far. I have a friend who took one flight lesson , loved it, got to land the plane himself , but it is too expensive to continue. Meanwhile they just spent $40K on a brand new Toyota SUV.
