I purchased an Ultimate Arduino Microcontroller Pack (you can order the pack online at Makershed or buy it at your local RadioShack). The pack comes with an Arduino UNO and ton of components. It would probably be cheaper to buy components as I need them for my projects, but I like the convenience of a starter kit. I also purchased a GPS module Digikey.com and a USB cable (it s too bad that the pack does not include the USB cable). The GPS receiver has a built-in antenna, but getting one with an external antenna would probably work best. From the pack, I ended using the Arduino UNO, the mini breadboard, a few stackable headers, jumper wires and the LCD screen.
