Digital and brushless tech in servos has increased performance - but there are still very good analogue/brushed servos available too.
Futaba is one of the best brands and would be a wise choice. They also tend to fit Tamiya cars well.
Look for 0.1s/60deg speed, and 6kg/cm torque for touring.
From the current Futaba range, the S9402 (analogue), S9452 (digital), S9551 (digital low profile), BLS451 (brushless) and BLS551 (brushless low profile) are all excellent touring servos.
