Original Arduino Uno
Cytron Maker Uno X Fully Arduino Compatible (with output indicator LEDs)
Cytron Maker Uno X currently available at Amazon
I prefer the Cytron Maker Uno due to its compatibility to the original Arduino Uno and the fact that every digital output pin has an LED that can be enabled to indicate programming results without having to wire an LED on the included breadboard. This saves a lot of time when learning basic programming. It is also a much better value since it does include the breadboard at a total cost of about half that of just the Arduino Uno by itself.
