For my two cents (actually with the current exchange rate it's worth $1.34) I think folks who are really into making good quality 'cue and not those who get caught up in the fads, take their time to research what pit they are getting.
Doing an overnight cook takes planning (already said), patience (already mentioned), a few good quality cigars (I'm partial to Ashton VSG's) and some good friends.
In my humble opinion, the "gadget guys" are like the kids who buy the body kits for their cars but do no mods to the engine. Let me step back for a sec, when I say gadget guy I mean the people who buy the latest, greatest, as seen on TV smoker and have no idea what to do with it.
As for a pitmaster (cause I'm just bored today) that is a person who knows that BBQ is an inexact science and each time you fire you pit you learn something. BBQ College is a school that confers no degrees but class is always in session.
