Only one word for ya'...Stratocaster. 
So does this mean its cheaper to build your own pedal than to buy one? Those things run at least $70 per pedal.
Generally, yes, but some of them, you'll still shell out for.
I really want to build a UniVibe, for instance. That's still about $80 out of pocket... however, they are upwards of $300 for the boutique clones, so...
On the flip-side, you can put together a good fuzz face for about $25.
What gets you are the switches (those 3PDT switches are about $6 each), and the enclosures--usually about $9 each.
Everything else is pennies. Literally. Except maybe good NOS transistors and stuff.
I was just saying that even though it's cheaper, you end up not doing it for the savings, you do it for the tone addiction.
