I wonder if anyone had any experience with mac extended warranty from Adorama or any other retailer. Note that Mac here doesn't mean Apple computers. My personal experience is that bestbuy, Circuitcity extended warranties are useless and waste of money, Apple is worth the money. Reason is I am asking is that I might stretch my budget to buy L Canon lens, which is refurbished, so only 90 day warranty. Really can't decide with my purchase, Canon makes hard choice producing only some lenses with IS, only in some length. I am getting an impression that ideal situation would be 3 lenses. While I would like to have no more than 2.
