Need basic JPG camera for Arduino

I am looking for a basic JPG camera that I can attach to an Arduino Uno, capture photos, and upload to a SD card. I see tons of discussions of the OV7670 which seems to be very negative (can’t get it to work, etc). Can anyone recommend a camera known to work well, and a source? Thank you very much.

..as U've seen. keep away from that one..
Do reserarch.. confirm others success and have code ready.

Grove (Seeed Studio) also has a serial JPG camera. http://www.seeedstudio.com/wiki/Grove_-_Serial_Camera_Kit
