Ask to see samples of their advertising plan and what they've done to market past listings. If you find an agent you like here on Trulia you can always have them do the agent research for you and make a referral.
Over the course of time, with your transaction, you may need to follow their advice even though you disagree with them. So, be sure you both can work together, through thick and thin, before you make the commitment John talks about. It's a good partnership between you and your agent that will help make your sale successful.
