nice 5-7 megapixel p&s {sony p200}

Hi,
I am looking for a nice 5-7 megapixel point and shoot. I like a lot of action shots. minimum of 2.0 screen and relatively small{not credit card small}.I went to best buy just to check stuff out and saw the sony p200 which i liked a lot and a sony w7. I thought the w7 was a little big and hefty especially for carrying around mountain biking.Help would be appreciated.
Thanks a lot!!! :cool:

also about how many pics would i get with a 512 in 7 mp mode? thanks!!!
