What card reader do you use or would you recommend? I was looking at the sandisk readers and the camera store suggested the Kingston TravelLite. I'm planning on ordering the Sandisk Ultra II 2GB or the Sandisk Ultra II plus which has the built in USB port. What are your opinions on the Sandisk Plus with the USB built in. I have a PNY 1GB, is that alright to use in the D50? Are there any brand of SD cards to stay away from?
