If you go with dyndns.org, you don't need to get a new router with  
dyndns support.  You can run ddclient on any linux box behind any  
router.  To setup using dyndns and ddclient you do the following:

1) register for a dyndns account
2) pick a hostname
3) download and install ddclient (I used apt-get)
4) configure the /etc/ddclient.conf file
5) start the service (/etc/init.d/ddclient start)

Here's a sample /etc/ddclient.conf file I have on a FC1 box running  
behind by DI-514 wireless router:

daemon=300
syslog=yes
mail=root
mail-failure=root
pid=/var/run/ddclient.pid
login=$login
password=$password

use=web
web=checkip.dyndns.org/
web-skip='IP Address'
wildcard=yes

server=members.dyndns.org
protocol=dyndns2
host=$host


Fill in the values for $login, $password, $host.

Of course if you want to create your own system, you can use the  
following command to find out your external IP address:

   lynx -dump http://checkip.dyndns.org

Good luck and let us know how things go.
