Scott Edwards' Mini SSC-IIs get my highest recommendation if you need
to control several servos.  If you only need to control one or two
servos the SSC-II is probably over-kill.  A BASIC Stamp is the easiest
way to go, and a PIC is the least expensive.

Have fun,

3) Are their any driver chips that will allow me
to input a digital value and get the correct corresponding Pulse Width
Modulated output to drive a hobby servo like Futaba, etc.?

There is probably no ready-to use chip to control a servo with a digital
value. But you have two solutions :

1. Try to program a pulse width modulated signal output. You need a fast
"brain"...
2. With an digital to analog converter and a 555 chip, you could
probably convert an 8 bit signal to the right pwm... Didn't test it
though.

For the first solution, I've already made a simple servo tester, which
use a standard printer port, and a windows proggy (sources included).
You can control up to eight servo's with one parallel port...

Good luck !
