I did find a forum of EEs talking about hacking something together out of a set of 555's, but that's way harder for me to do than program a cheap microcontroller.
If you google "Servo Tester" you'll find a lot of different options for cheap (less than $10). I've used a generic one (don't remember where I got it from), and it worked pretty much as expected with PWM motor controllers. If you can find it on CD, I think Ether posted something about one that he recommended a year or two ago.
