I've bought nearly every single digit dollar cost thing on ebay with "arduino" in the title multiple times over in my short amateur stint teaching local kids beginning robotics classes. I almost always buy one of the sparkfun or Adafruit units to start with. In my experience they save 2-4 hours of intense googling and Chenglish translation on your first pass at the hello world of the new device. If you're just buying one, get the sparkfun and be glad you can slip then a 20 to spare you the effort.
