Buy a map? This might work for the generic deathmatch server, but not for the kind of servers Id run.
If you cant map yourself, get a mapper for your team. But buying maps from some external guys just ruins the gameplay feeling as external guys cant know the servers setting good enough.
If the server doesnt have any setting at all, it probably isnt worth playing on it, so I dont consider that case.

Also people always refer to "my server". How is it your server, if half of it is just bought from some guy?
