There is a difference between being cheap and buying appropriate electronics for the airframe. There is nothing wrong with Hitec servos, at least not with the 30 or so I have used. A 1/4 scale cub does not need expensive, hi-torque, hi-speed servos. Nor does it even need digital servos. Its not a fast plane and its not a particularly aerobatic plane. I would't recommend HobbyKing but any full-size offering from Hitec, Futaba, JR, Spectrum, Airtronics that meet the recommended torque specs for the plane's control surfaces will be more than adequate.
