Providing you have access to a PC/Mac, the easiest way to learn is to hook a synth up to your PC and get some free oscillator software. For Windows there are a number of free applications, I personally use (and would recommend) Visual Analyser. For Mac and Linux I don't know of any, but I am sure they exist.
Most stand-alone units are overkill for audio waveforms (they're aimed at electronics engineers, who need tens if not hundreds of megahertz of frequency range), and they are often pretty big and heavy. Some exceptions are units like this one (which is basically an MP4-player with custom firmware). That said, nowhere will your waveforms look as good as on an old analog beast of a scope, preferably in a dark room (example).
Doesn't get much cheaper than these: http://www.amazon.com/Signstek-Pocket-Sized-Handheld-Digital-Oscilloscope/dp/B00DRUWPM6
Upgrade the firmware, you'll find simple instruction online. Very cheap, small, and light.
