Any video cameras/camcorders you recommend?

-I want to buy a video camera with a good quality picture, but is still affordable. Also, I'd like a camera that I can put an SD card in. I like the size and picture of a Flip, but there isn't a way to increase memory besides buying a camera with a larger memory. Currently, I have a Sony Handycam, and that works well. However, I'd like a second camera that's not as expensive. Any suggestions?
