We just closed on our house last month, with Samantha Griffin as our agent. Although she worked with as buyers, she did a fantastic job -- very diligent and knowledgeable, and when she didn't have the answer she got me the information pretty darn quick. I think she'd be great for you as a seller's agent.
I suspect you might get a lot of positive answers, and they all are probably pretty good agents, but I have to heartily recommend you at least give Samantha a ring (352/427-5923) or email:
samantha.griffin@thevillages.com.
Best of luck.
