Refurbs most often aren't refurbished at all. Most often it's a new lens that someone bought from a large retailer with liberal return privileges, shot it a little bit, decided they didn't like it, and returned it. Nothing wrong with it, but the retailer can't really sell it as new again. So, it goes back to Canon, gets repackaged in a white box and sold as a refurb. In some cases there may actually have been some problem with the lens, but it was within the retailer's return period, so the customer returned it to them for an exchange rather than sending it to Canon under warranty and being without a lens for a couple of weeks. Again, the retailer sends it back to Canon, it gets repaired and sold as refurb. Basically the question is whether the price difference is worth the warranty difference (90 days vs. 1 year). Sometimes the price difference is pretty slight. Puzzling to me is why you can often find Canon refurbs at B&H for less than they sell for on the Canon site.
