Buying used lenses from ebay etc. - too risky? what do we think? I'm after a canon 70-200 f4 L and they seem to be pretty good value new anyway but i have limited experience in buying lenses second hand. Cheers

Nice fellas and fair price. Yes, they might be a touch more expensive than getting from a person, but they carry a 6 months warranty with what they sell and as much friendly advice as you like etc. and good coffee too.
