My latest Arduino project is a device that logs into my bank and displays my checking account balance on an analog gauge (like a gas gauge on a car).

Using the WiFi capabilities of the YellowJacket from Async labs, every five minutes it connects a web service running on my web server.  My web service uses screenscraping to log into my bank account and determine the amount.  It converts this value to a range from 0-255 which is sent back to the Arduino.

The Arduino outputs this value on an analog pin which is connected to the gauge.  If my account has $500, it is "full".  If it is $0, it is "empty.

The YellowJacket was $55.  I got the gauge from Skycraft for around $10.  I also bought a nice enclosure box to put everything in, which was $5.  So, all told, the project cost $70.  That being said, the YellowJacket can be used for other projects (like my TwitterSwitch), so it isn't like I spent $70 just on this.
