There is also the MDC "Really Bare Bones Board": http://shop.moderndevice.com/products/rbbb-kit

The "real" arduino is not too badly priced.  To build ONE would probably cost you more than half of the full price, plus whatever you value your time for assembly.  (expensive bits: CPU and USB chip at about $4 each, PCB at about $5, maybe $3 worth of connectors...)  Real cost savings show up when you start buying in quantity, and/or you can eliminate parts of the circuit because they're not relevant to your particular project, and/or you can simplify the PCB and use "parts on hand" to limit the components you actually need to buy.
