Test Equipment Oscilloscope

Super-simple, inexpensive oscilloscope?
Oscilloscopes are rather expensive; after all, they're quality equipment used to test all sorts of electronics. They have countless applications. But I need one that can serve only one application, and so I'd like not to blow a whole lot of money. I just need a monochrome oscilloscope, which I am going to partially disassemble and install into a special case along with a speaker, to visually represent the speaker output. I'm probably going to use perhaps 3 or 4 eventually, and for something that won't be utilizing advanced functions, I'd like not to spend $400 or even $70 (ebay) on each 'scope. Are there simple, cheap oscilloscopes?
PC-based solutions are useless to me. I am wanting an oscilloscope *built-in* to each of my speakers, always showing the speaker output. It's just for decoration.
...Or have you considered building one - NO! - not the whole thing, but a very simple (and very low-cost) PIC - based interface with which you can use any TV set as an oscilloscope...?

This, together with some 5" B/W TV sets which you can buy for a few dollars new (like brand "Curtis"), and you are well below your $70.- mark.
