I am rocking the Blue Bird BMS660MG for my steering servo (metal gears, heatsink). [email protected], you can't beat that for the $40.00 one of these things cost. I have heard that these are unreliable, but mine is working great. Its better than the Hitec 645 that I use for my throttle servo. Its also 1/3 the cost of the JR servos I used in the past. I would recommend giving one of these a shot.
