Some of us who are doing commercial things and making a lot of purchases from the commercial suppliers still buy some stuff from folks like Sparkfun - it is pretty handy to be able to prototype an idea using a BOB. If you want to bargain basement shop, why not go all out and order some crappy Chinese knock off that does nothing to support the community? But if you are a hobbyist I would suggest you support companies like Sparkfun, Adafruit, EMS, Jameco, etc. AFAIK, Mouser does not do a lot of development, support, or tutorials for this - they are primarily targeting the professional/commercial market, while Sparkfun is primarily targeting the hobbyist market. The Mouser price is closer to $40 than it is to $30.

Not sure which Arduino or Arduino-compatible board is right for you? Check out our Arduino Buying Guide! The Mega 2560 R3 works with all existing shields but can adapt to new shields which use these additional pins. The other is a not connected and is reserved for future purposes. One is the IOREF that allow the shields to adapt to the voltage provided from the board. In addition, there are two new pins placed near the RESET pin. The Mega 2560 R3 also adds SDA and SCL pins next to the AREF. Never fear for accidental electrical discharge, either since since the Mega also includes a plastic base plate to protect it!

It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. The Arduino Mega is a microcontroller board based on the ATmega2560.

The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux). Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/ Wiring language.
