Amazon offers the Sony Cyber-shot DSC-TX30 18-Megapixel Digital Camera in Black, model no. DSC-TX30/B, for an in-cart price of $180 with free shipping. That's the lowest total price we could find by $28, although we saw it for $10 less in June. It's water-, freeze-, dust-, and shock-proof and features a 5x optical zoom, 3.3" OLED touch screen, 1080i movie capture, optical image stabilization, and SDHC card slot.
Of note, it's also available in Pink for $190.02, or Orange for $192.
