Two things to really concentrate on: sound has to be good. I don't know the model numbers, but a good boom mic is something you really can't cheap out on. Off mic dialogue spoils the suspension of disbelief in a hurry. Another consideration is to really plan your shots around editing. With a tip of the tam o' shanter to Hudson UK and the rest of the Intrepid crew I would point to their latest vignette as an example of really smooth editing. Bumpy edits are the kind of thing that people may not notice consciously, but they definitely are a distraction.
