Staples.com had the I/O Magic 500 Gig external hard drive for $99.99 (after $30 rebate).  I do not have a direct link to this so just go to Staples.com and in the search bar type in “Gigabank External” and it should appear.  Notice that the price for the 500 gig is THE SAME as the price for the 250 gig.  Enjoy the hard drive!
