At your budget you'll have some difficulty getting the transformers needed to step up the voltage out of your amplifier.

If you're real good at scrounging, and you go to ham fests and Goodwill stores a lot, you'll probably be able to find an old tube amp that you can steal the transformers out of pretty cheaply (unless the tube audio maniacs have beat you to the mark!). You can even use the power supply transformer to make a bias supply.

The rest of it can be real cheap, but locating all the materials is a lot of effort. Once you find everything you need, you'll know where to go and will be able to make many more speakers quickly, easily, and cheaply.

Good luck.

Found this site last night. <www.buckeyeweb.com/russknotts/home1.htm> You can buy parts, build your own frames and have a good time. More expensive than what you are looking for but has good pics and explanations. I also want to mention that I have seen some very good stats that the panels for stretching the mylar looked like the 1/2 " thick crosshatch panells used in flourescent light fixtures. Not sure if that was the origin or not.
