I have a Kodak DX4530 , 5.0 megapixel, 3x optical, it has a built in 32 mb memory inside the camera itself with a slot for a SD memory card. I bought a 256 mb SD card which is plenty big. The built in memory would pay off if your card was damaged in the field... as you could still take quite a few pics on the camera's memory.
You can choose the detail level/resolution you want simply by changing the setting in the menu on the camera. It also shoots video w/sound( I think you get 30 secs of video per 16 mb memory??) , uses either 2 AA or one of the crv3 lithium batteries.
I got it for under $300. I bought the docking station(@ $90), so I just have to sit it on the station and hit a button to input the pics/video onto my computer. It also charges the rechargeabvle batteries (included with the docking station) while it sits on the docking station.
I love it.
