Motorcycle for beginner used and cheap?

ok, i am liking the gas mileage on motocycles. i like the crotch rocket look. but i would rather start out with something slow and stable. but with the same bodystyle. i will have about 1000 dollars to spnd, i wanna get something some one has probly dropped a few times, but it still runs ok, you know? i dont need anything pretty. cause i will probbly drop it never rode a bike b4. but i like the simplicity of the motor and the gas mileage. i dont want a moped... doesanyone have any idea what insurance will do? i will have liability. will it go up or down? anyone know? im a car guru, but motorcycles to me are something new
