http://arduino.cc The only thing you need is an USB cable. A lot of memory, a bunch of timers etc and pretty fast. The card is open sourced. Buy it, build it or get a clone. C subset for programming. When your finished with your project, get a Mini or Nano and make it supersmall. Besides that, it's cheap.
I love it, I even brought one on the vacation. :) A lot of open projects, examples and good documentation. Have a look at http://www.freeduino.org/ too.
