How about the PC joystick port?  Can't get much cheaper than that! And
it's also very well documented.  ;-)  There are 4 digital inputs and 4
analog inputs.  The analog inputs actually aren't very good at doing
analog input, but they can easily be used as digital (pulse) outputs.

I also found this site with a lot of dedicated interface offerings:
