May I suggest you try www.epicurious.com? I have never had a bad recipe from that site, and most of them are gourmet-level recipes. Just type "cheesecake" in the search box. Also, below the recipes themselves are responses from people who tried them, which is a bonus.

Good luck! Just remember that when the cheesecake has cooked the right number of minutes, it should not appear done. Turn the oven off and leave the cheesecake in the oven for an hour with the door closed. Then let the cake cool completely before removing it from the pan and putting it in the refrigerator. It's better next day, by the way.
