What ever is easiest, cheapest all while making it look it's best to sell for the highest price. But with that said, I wouldn't spend a whole hour longer and spend $10 just to make $15. Fast and decent is the name of the game. I spend 10 minutes making my washers and dryers look excellent. If it would take me 30 minutes, I probably wouldn't make them look as good, I'd settle for a little less quality. The name of the game is flip it fast, make quick money and do it again.
