New to servos, need some help on deciding which to buy

Okay so you are saying that I would use digital servos.

I just found out that the people over at HSD use the Hitec Zebra ZS S2113 Std Servo which are analog, and the issue is that they aren't being made anymore, Is there a comperable digital servo?

Also if I got analog servos, but still wanted to use the TLC5940 to control them (which outputs 16channels of PWM signals), would I need to do this? http://dev.emcelettronica.com/how-to-use-pwm-to-generate-analog-or-analogue-voltage-digital-circuits-part-2
