Default Inexpensive Servo?

I'm looking to get back into 1/10 RC and was wondering what servo I should get for my 1/10 electric touring car as a steering? General, high speed, or high torque?

I've been using the Futaba S3003 in the past without problems but might consider an upgrade now. What kind of torque and speed value is good for a steering servo?

Potentially looking at TowerPro High Speed Servo (MG995). What do you guys think?

I've had excellent results with the Hitec HS-925MG servo. Lots of power and good speed with ball bearings and metal gears. It isn't digital, but more than enough for my skills.

Or has anyone tried Scanner RC SSV-9766MG? That spec looks comparable to the Hitec HS-925MG but for half the price.

The power output on that servo seems very low at only 38 oz/in @ 4.8V or 43 oz/in @ 6.0V The HS-925MG has 85 oz/in @ 4.8V and 107 oz/in @ 6.0V

Speeds for the two servos are virtually the same.

I see the spec as:
4.8V:
6.3kg/cm , 97oz/in
0.11sec / 60 deg at no load

6.0V:
7.4kg/cm , 106 oz/in
0.09sec / 60 deg at no load

I was using the wrong servo number. My bad.

Looking at the specs of the 9766, it almost looks like the Hitec servo specs, so it might not be a bad choice?

Does metal gear servo help the reliabilty of the servo that much more?

MG help keep from stripping gears inside servo usually due to impacts - pretty helpful for offroad, but if you running onroad and rarely hit anything, there won't be that much of a benefit. I don't use anything but MG servos though.

When you change to MG servo, you need to change servo saver to one made for MG servos so they both work together.
