I've read that site before. Just to clarify, the breadboarded circuit is an arduino equivalent right?
Yes, it's a full Arduino board on a breadboard. If you leave out the communications part though, it's just a standalone ATMega on a breadboard as you will want it in your finalized project (except you want to have serial communications to your project, then you have to implement some way of communicating of course).
edit: Btw, there's a great overview for all boards on http://arduino.cc/en/Main/Hardware. It's got pictures of all the boards, so you can look which one have a DIP ATMega, which always comes on a socket.
