Hey guys, I just picked up a Lazer ZX-5 FS2 SP kit for a pretty good price (how's $390 posted sound

) and I'm not sure what servo to get. I've seen the Savox an KO Propo one's but they a bit more than what I wanted to spend, I wanted to keep it under $50AUD if possible.
It's gotta be good quality, metal gears and ballraced and suit a Futaba reciever. Thanks for any advice.
