Here's another:
This one is an HS-311 geared to 270 deg.
As you can see, this one has no trouble doing full scale. It seems to have lots of power. And it's pretty cheap. It's a bit largish but stiill very usable.
Here's a comparison of the three servos I've used so far, showing relative force, speed, and price:
#1. HS-225BB__ 54 .14 $18
#2. HS-55______15 .17 $10
#3. HS-311_____42 .19 $8
Edit: Added first one:
