I'm not aware of of any aircraft costing less than the 8 figures equipped with FBW. It's a LOT of added complexity/cost for very little gain in anything that isn't either dynamically unstable (e.g. modern military aircraft) or so large that the flight controls can't be comfortably operated by hand, and is rare even in the bizjet and smaller airliner market.

On all small aircraft (and some larger older ones, DC-3s for instance), muscle is the only thing that moves the control surfaces. They're very well designed and counterweighted so that the required effort is quite minimal.
