BuyDig offers the refurbished Sony Cyber-shot DSC-RX100 20.2-Megapixel Digital Camera in Black for $349.99 with free shipping. That's $50 below our mention of a new unit from last spring and the lowest total price we've seen for this camera. (It's $148 under the best price we could find for a new unit today.) It features a Carl Zeiss Vario-Sonnar T f1.8 3.6x optical zoom lens, 3" LED, Exmor 1" CMOS sensor, 1080p video capture, optical image stabilization, and SDXC card slot.
Note: A 1-year warranty is included, but it's unclear who backs it.
