As a follow-up to my other thread:
TigerDirect now has the 2TB Western Digital - My Passport Ultra portable external hard drive for $99.99 after coupon code WDF133699. Use Shoprunner for free shipping.
This is the same exact hard drive as the other one I posted about, except this is the 2TB version.
Once again, highly rated, best seller on amazon. Plus you can probably combine with a cashback site to save a little more.
