Well I have just put another box over to Bind so we will see. Pre this 
version of Bind (9.3.1) the look ups were slow enough that I would 
notice lag on web page loading. So far I haven't so may be there is 
reason for me to move...

It does become more complex as my DNS servers are also authorative for 
various domains as well as caching and Bind does make that easier, only 
needing one IP address (I know there is a patch but I have never quite 
got there). Who knows? Only thing that is certain is I am more confused 
(Which doesn't take much) as to a preference.
