Re: Quieter motors?
If you want to use servos, you're unlikely to find anything else much quieter than these, for reasons already stated.
If you want to use other motors, you can probably find a number of different ones (they sell DC motors in the parts racks at Radio Shack, for example). Unfortunately, since motors typically don't have a controller built in, you need to obtain a speed controller to be able to do anything other than use them at full power in one direction. One option is speed controllers, but these tend to be rather pricey and in most cases overkill for a motor the size of the Vex ones.
Another option, probably a bit more realistic for small motors, is to get an H-Bridge. It can do the same thing as a speed controller for a much cheaper price; they can't handle nearly as much current or voltage, but should be suitable for small motors. You can find them at most hobby robotics places online (I don't think I've ever seen one at an actual store before), one good place to look at is acroname.com or anywhere that sells Sumobot components. You can probably obtain small DC motors from such places as well.
I don't know what kinds of programming are required to use an H-Bridge (I think they can be used the same as a speed controller), but I'm sure you guys could figure it out since you're using these for programming.
