I just ordered the GRANDTEC GEZ-1000. It takes a VGA signal and converts it to composite (yellow RCA) and svideo. So you will need the VGA cable as well. Also it gets its power from USB, however, you can get one of the USB travel chargers. See this:

A few places have the GEZ-1000 as cheap as $31 with free shipping. The travel chargers are about $10+shipping on ebay. So for about $45 you end up getting the video converter, a travel charger, and a USB cable for your axim. Not a half bad price.
