Where to buy lenses other than Ebay?

Other than EBay where do you guys buy your lenses from?
I'm in the market for a Canon 24-105 F4L and Sigma 100-300 APO IF HSM DG.

(OCUK don't sell lenses so we shouldn't have any competitor issues!)

Sure OcUK don't sell lenses but the other shops that do also sell the same products as OcUK.....unless you find the only lens only seller in the World
