Another reason you might want to not forward to your ISP's name server(s) 
is that they may go down, and if they go down, you go down.  They might 
change their IP addresses and once again, you go down.  I am a consultant 
and I run into this problem a lot.  Customer calls in and their network 
has been down all day, they have BellSouth T1 service on one line, Cisco 
TAC on another line, Checkpoint/Nokia support on another and me on their 
cell.  I say "you don't happen to forward to your ISP's name servers, do 
you?"... Problem solved.
