There are several good ones in the $60-70 range
Personally, I like the Savox 1251MG low profile servo. It's fast, has plenty of torque and it's a good price.
There are a few other brands with near identical specs to this servo. Spektrum has one (S6070) and I believe Orion has one too.
A lot of guys swear by KO propo, Hitec, or Futaba servos, but the only servos these companies have that are close to the specs of something like my Savox, cost twice as much or more.
I've never had a problem with glitching, even with no rx cap, but I've heard of others having issues, because these servos tend to be a bit power hungry.
