I have to say, I was very, VERY intimidated by the Xbee from the long post on here about them but I have to say, I had mine up and running in about 10 minutes. Super easy to use and all the instructions you need are right there in the forum topic. And, they aren't as expensive as you might think. There's a great place to get them from call Arrow. This is the one that I got. Free overnight shipping...it showed up by 10:00 the next morning and I didn't buy until almost 8pm eastern.
