Doesn't the correct answer depend on how sick the patient is? Occupied or vacant? A knock your socks off table setting will NEVER compensate for a home that smells like a kennel.
A clean, 2000ish waterfront condo only staging requirment may be to pull open the shutter to display the big water view!
For a dated home I leverage large display easels with graphics from the Lowe's and Sears (commercial) design centers.

I am an ASP Realtor, as some of the other Realtors have already mentioned. When I have a listing that is not high end, I have some furnishings & accessories that I used to create vignettes.
Sometimes, yes - there's enough material to work with that a little bit of re-arranging and de-cluttering can make the home look like a model.
Often, however, that's not the case. As an Accredited Staging Professional, I feel that I can speak authoritatively on the subject, and all re-decorating isn't "staging" any more than every middle-school auditorium stage is a "set."
