Alternative to Airport Extreme + USB + Time Machine Support
So I've been using my old trusty wireless router (Linksys WRTS54G) for quite some time now and I decided I need to upgrade to N-draft and something with USB support for wireless time machine backups. The only problem I've been running into is that I can't locate any decent rated routers out there which do not conflict with using OS X. Essentially I would settle for something without USB support and keep plugging in my portable HD into my macbook each time I need to backup, but is there anything out there that anyone can suggest? I just can't justify spending $175 for a Airport Extreme.
