Canon offers the factory-refurbished Canon EF 70-300mm f/4-5.6 IS USM Telephoto Zoom Lens, model no. 0345B002, for $199.99. With free 2-day shipping via coupon code "HOLIDAY", that's $87 under our refurb mention from ten days ago and the lowest total price we've seen. (It's $149 less than the best deal we could find for a new one.) It features improved Image Stabilizer Technology compared to the original Canon EF 75-300mm IS zoom lens, as well as a lighter weight and smaller diameter. A 1-year Canon warranty applies.
