Adorama via eBay offers the factory-refurbished Canon Speedlite 430EX II Flash, model no. 2805B009AA, for $169 with free shipping. That's a buck under yesterday's expired mention and the lowest total price we've seen. (It's also $80 under the best price we could find for a new unit.) This hot shoe flash for Canon EOS and PowerShot G series cameras features an AF assist beam, automatically zooms to match a compatible camera's image size, and purports to have a "virtually silent" flash recycle. A 1-year Canon warranty applies.
