Looking for '02 or newer Altima

Hi! Newbie here. I've read over several posts about '02 Altimas and their problems. I owned one and had no problems at all until I wrecked it. It was a beautiful car, the best I've ever owned. I'm looking to buy one as inexpensively as possible. Any ideas about auction sites other than Ebay? I almost had a bad experience with them when I contacted them to verify that it was legit. Anybody have experience with online auctions and can provide advice? Can anyone provide good feedback for the '02 Altima? I was really surprised at the negatives posted. Could you return the car under the Lemon Law? Anyway, can someone provide advice on where to find a reputable auction site? Thanks.
