Has anyone purchased an extended warranty or there camera? I'm sure some of you have them. I'm looking for a good deal on one from a reputable seller. I hear good and bad about all of them. I've seen the ones from Amazon(Warrantech), Squaretrade, and I did get the camera from Best Buy so the Geek Squad is an (expensive) option. Any thoughts on any of them. I'm looking for accidental damage overage for a NEX5 and maybe the extra 55-210 lens.
