I've had a Radio Shack 22-812 digital multimeter (about $70) for 7 or 8 years. It sat out in a cart in my shop for when I worked on cars, so I pretty much forgot about it (I always have my Fluke 83 close at hand). But it has a serial port and today I sat down and figured out how to talk to it with some help from the web.
If you want to do some simple data logging, it could be a solution, especially if you don't already have a digital multimeter.
I posted a python script at http://code.google.com/p/rs22812/ that will do the work for you.
Once you've installed python and PySerial, go to a command line and type python rs22812.py and you'll start logging to stdout.
