I am about to connect up a Deventech compass module which use I2S for
communications, using a Deventech USB to I2S adapter. I'll let you know what
I think of it. I should be doing it Friday or over the weekend. See
http://www.acroname.com/robotics/parts/R117-COMPASS. This is the same one
you have the URL for from Robot Electronics. 
I've had an interesting experience with software development on the Android
cell phone (the Google Phone). It has compass and accelerometer. You really
need both to keep the compass accurate when tilted.

Anyone have any suggestion on a good compass circuit to use with an
Arduino/Sanguino board?
Saw the Honeywell HMR3100, but I don't think I want to have to deal with the
Serial Tx/Rx.
Don't know if this would work:
Or maybe a Dinsmore 1490 or 1525:
