Looking to buy third DSC-P200

I reviewed many websites before choosing the P200. I bought the first one in June for my son. I played around with it for a week before giving it to him, and I really liked the size and ease of use. I bought the second one the middle of July and took 200 pictures in Alaska. The pictures turned out perfect. I took great pictures through the glass window of a train while the train was moving. The only problem was the camera froze up after an hour of taking pictures of glaciers. After it warmed up it was fine. Now I'm trying to figure out where I can buy a third one for my daughter. I went on-line and our Radio shack still has some for $229, more than the $199 I paid at SAMS. The camera has been discontinued so they are hard to find. Too bad.
