I'd also look under www.boat.com
and check out prices, location and type/size of sailboats. You can reference reviews of any boat you are interested in on Sailnet and boat.com. Before you buy, clearly a surveyor should be used for your protecion and understanding of any weaknesses the boat or its equipment has, which will help establish a fair price. To single hand, I'd make sure any vessel has gps, radar, autopilot, head sail roller reefing and main reefing, self tailing winches and a windless. I might also consider a cutter with two head sails roller reefed to permit easier sail management. Good luck in your search. You should check out Oriental NC, the self described sailing capital of NC for possible boats as well.
