Just after some advice on what would be best for me 
To explain my situation I have an Linksys NSLU2 with 2x 500GB hard drives attached to it so I can access my files anywhere via FTP and also acts as a web server and itunes server so things like accessing anywhere via mobileme are irrelevant.
So what I am really interested in though is compatability with time machine... Would an Airport Extreme with a USB hub and a printer and a 500GB USB drive work as well as time capsule?... there's a fair chunk of money difference between the two if you already have a USB hard drive knocking around so other than having an all in one device are there any other benefits?
Also whichever route I took my ADSL is connected to a Netgear DG834N wireless router... id prefer to keep this as it allows me to input my dyndns account details and update with my current ip address... would it just be a case of hooking up the WAN on the Extreme/TC to a free port on the DG834N?
