cam selection

hey guys. im trying to choose a cam. the erson cams are all mechanical. and my dad keeps telling me im not going to want to deal with that. he says go hydaulic, but i can only find a comp cam and its back ordered. how much maintnence is a mechanical cam. and when did they switch over the slant sixes. my engine build isnt going to be wild. i just want a cam that has good usable power from the 1000-4000 rpm range. i would appreciate any feedback.thanks!
