HD SD Camcorder Recomendation

Hi Guys,

 New to the forum...............looking for recommendations for an entry level HD camcorder to replace our Panasonic dvd cam.  Just need something for family vacations and for recording our drag car at the race track--not interested in low light or fancy shootings-in fact (and don't laugh), we are really impressed with the video quality of our Aiptek action HD cam that we use inside the race car.  The budget is under $400.  What can you recommend??
