I had much more success with PIC while I was just getting started. I tried to get a simple starter kit from Arduino and just couldn't get a good basic kit without spending more than $100-200 nickel and diming the setup together. Got a great little starter kit from PIC for about $40 and it has everything: IDE, programmer, starter board with built in circuitry for demos and tutorials. One purchase. Also, the PIC environment was very easy to get set up and working. I was playing with it within an hour.
