Why buy a 5 - 11 dollar part you're not using all the features of when you can use a couple transistors and some discrete parts? http://www.arduino.cc/en/Main/ArduinoBoardSerial If you need RS232 levels for some reason you can find a blizzard of cheaper alternatives. I've used the ADM202, 75c1406 which are under a buck at some suppliers depending on qty. Another way of getting those levels is a 99 cent wall wart. I've done that to and it works for extended runs.
