I am looking to find if the EFG80 is better than my NSLU2. My NSLU2 has performed flawlessly, but is the EFG80 faster? I have searched all over linksys.com and they have little information left on this device. I have an opportunity to acquire 2 of these EFG80 devices for relatively cheap and would like to know if this is an upgrade to my current set-up or not. Thanks.
