It depends upon how many PCs / servers you have and what functions these 
perform.
If you only have one or two computers, do not run your own servers then 
you have no need for your own DNS.
If on the other hand you have multiple servers and computer workstations 
and want to be able to connect to these by name then running DNS makes 
lots of sense. If you host your own web site and email etc then having 
your own DNS (or masquerade) saves bandwidth and more particularly time 
in DNS lookups.
