Guys, After watching a professional drop his 5D MKII after a drunken idiot ran in to him last weekend, I've realised I want to insure my own gear. Only issue is I don't have receipts for any of my stuff, including pieces like my Sony DSC-F717, Canon 350D and 17-85 IS USM etc etc. Are there any places who won't demand proof before making a claim if something were to happen? I fully understand why proof is required, I am literally asking because if all places insist on it, there's no point in me insuring my gear. Anyone got any advice to offer?
