Getting site administrator(s)

Scenario:
I needed to find out atleast one user who is site admin , for purpose of creating a SPUserGroup.

Also for someother requirement I wanted to find out the list of users who are site admins.

Solution:
I love object model , I am sure you can sense that ;-)

Code:

     private SPUser GetSiteAdmin(SPWeb web) 
        {
            foreach (SPUser user in web.SiteUsers)
                if (user.IsSiteAdmin)
                    return user; 

            return null;
        }

        private SPUserCollection GetSiteAdmins(SPWeb web)
        {
            SPUserCollection users = null; 
            
            foreach (SPUser user in web.SiteUsers)
                if (user.IsSiteAdmin)
                    users.Add(user.LoginName, user.Email, user.Name, user.Notes);

            return users;
        }
