pmorici has good recs (XBee is especially fun), but the Arduino starter kit alone can be found here: http://www.sparkfun.com/commerce/product_info.php?products_

  Just as a heads up for anyone considering buying the kit regardless of the $100 off, it's actually cheaper to buy the parts in that kit individually, and it's really easy to do that because they link all the individual product pages. Not to mention if there's any parts you want to buy more of, you can get volume discounts on that. I don't remember exactly how much less, but I believe it was ~$10 or so in total.
