DNS servers aren't going to change often, so you might as well hardcode them.  
If you're paranoid about them changing, twiddle the dhcp script to syslog the 
dns server addresses so you can look them up if you're having problems.

The *best* thing to do, while we're on the subject, is to run named on your 
NAT box, listen only on the internal interface, and point your home LAN 
machines at that interface address for a dns server.  Why you ask?  Well, then 
you're not NAT'ng UDP nslookup packets and you have standard DNS caching from 
a local name server.

fwiw, @HOME generally will do DHCP, but you still have one address assigned to 
you.  Obviously if you aren't using @HOME, YMMV.
