Matt,
Get the glider rating first, then get checked out in a light sport
powered airplane. The transition to light sport is easy and cheap.
You will only need a few hours in the light sport aircraft, you don't
need a written or any check rides, and you can fly without a medical.
If you want to get a private power rating, the light sport time counts
toward the power rating. This is the cheapest way by far to get both
ratings. It will get you in the air quicker and cheaper.
