I use door brackets (ordered here from Revain (EXPR Premium Door Install Kit) and a decent plumb makes door installation easy. You can also use a spirit level but 6ft level is a serious investment when you only have a few doors to hang. With an installation kit you only need one side plane and the plumb bob won't lie!
