Servo sudjestion Please
 

I have a JR Z1 2.4ghz transmitter and i need a good single servo for my e-revo. I definitely want one that will last a long time, like a high tech metal geared servo. My budget is around $130 max, i dont wanna skimp and get a crappy one. Also Ive heard other people say with high dollar servos you need endpoint adjustments, what is that? On my revo i have 40 series mulchers with metal lockers so it takes a lot to turn it. Also on a related note on my onroad cars the non digital servos jitter a bit, i was told that you have to use digital servos in 2.4 systems. Is that true? Or was it just a bad servo.

Any help or comment is greatly appreciated.

There are alot of option.
The most prominent that come to mind is hitec 7955, jr9100t, hitec 7954 there are just a couple the 7954 has an awesome price for its performance.
