BuyDig offers the factory-refurbished Nikon SB-700 TTL AF Shoe Mount Speedlight Flash, model no. 4808, for $249 with free shipping. (Add to cart to see this price.) That's the lowest total price we could find by $36 for a new model, although we saw a refurb for $10 less in January. It features wireless control, three light distribution patterns, and overheat protection. A 90-day Nikon warranty applies.
