I do run for Ko Propo, but the Futaba 9551 is a low profile servo with a good price point. The Ko Propo 3245, and the low profile 2413 are good servos from KO that aren't too much money. If you are looking for something cheaper, they have a line of mid sized servos that is right in between the size of a full standard servo and a low profile servo. The 2511 is a metal geared, digital "mid sized" that works great, and on a budget ($60).
