the airtronics servos are quite good. dont let the fact that they arent digital fool you; they are strong and fast. digital servos have slightly better resolution, but they arent inherently faster and they do burn more electricity. the airtronics servos are very good; i have three. strong, durable, and dont burn much power.
One other thing about digital is they are MUCH better at centering to the same point every time.
