I tell you, an old TV is a marvelous find...
and potentially a lethal one you should look into what sorts of electricity tv's and crt screens contain, its pretty awesome, but if you touch the wrong wire it will smell barbecue all the way to vegas. (since you live in the desert it cant be that far right?)
Oscillation, how about just using an old rc vehicle and attaching it to a microcontroller? Since you are a beginner, it will probably be easier than finding new motors and wheels to make a robot. Also, if you still want to make it from scratch, continuous rotation servos are probably the easiest, but you will normally have to pay about 10$ for one.
You could just use the motors from an old inkjet printer......and you could make a motor driver from scratch.
you dont need to be a continuos servo , you could buy a regular servo and modify it easily and save like 20 bucks. Continuous servos are regular servos that the company modifies by hand. It's the same as you modifying it.

It's the same as you modifying it.The Parallax continuous rotation servo costs around $12, so it's hard to say you can save $20 by buying something else. I believe Parallax has these servos specially made for them by Futaba, which means they can provide them for pretty much the same price as a standard servo of the same quality.- Ben
