Its a step beyond pedal kits, but I recently bought one of these:

It allows you to breadboard any circuit you want without soldering, but its very easy to plug your guitar into.
If you buy one of those, make an Electra circuit, and then fiddle around with component values, it'll open your eyes to how easy it is to make a pedal.
Oh man stewmac has more than I will
ever need
