Well, since we are paying (sometimes hefty) fees for listing, I myself would go for a 3 or 5 day listing if I wanted to make it short. The more exposure the better. The only item I could think of just off the top of my head for a one day listing would be concert tickets or other time sensitive items. But remember, ebay will have to 'index' every listing, I've had some take 12 hours to be searchable. There goes most of your exposure. And they pay particular attention to one day listings, as those are the ones favored by scammers and accounts that have been hijacked.
