Upgrading servos - which are some good ones to go with?

I am going to buy a AL5C without servos and would like to buy upgraded ones. Does anyone have any suggestions.

I dont need to move anything heavy, just looking for a little more speed and possible accuracy (if that is possible)

Any suggestions?

The AL5C uses the following servos:

1 x HS-422 standard-size servo (gripper)
2 x HS-475HB / HS-485HB standard-size servo (wrist, base rotate)
1 x HS-645MG standard-size servo (elbow)
1 x HS-755HB large-scale servo (shoulder)

I would recommend the following for the ultimate AL5C:

1 x HS-5485 standard-size servo (gripper)
3 x HS-5990TG standard-size servo (elbow, wrist, base rotate)
1 x HS-5745MG large-scale servo (shoulder)

To save some money this is another good option.

1 x HS-5485 standard-size servo (gripper, wrist, base rotate)
3 x HS-5990TG standard-size servo (elbow)
1 x HS-5745MG large-scale servo (shoulder)

Hope this helps.
