After doing my usual random googling I found this awesome Electronic DIY Kit site Some of the kits include things like...

Op-Amp function generator for $7.39 K81 - Kit 81 16C/F84 Development Programmer for under $27. Now thats a good deal. May have to order one soon.

Also there are several kits with complete schems in PDF format. Like this Audio to Light board.

There is alot of potential that I see in these kits plus alot of them are super cheap ( $10 and under )
