Standard Prime Lens for 7D Dillema

Ok in the end went with Tokina. I know it's an outsider and people don't value it as much, but my decision was purely based on the quality people were getting out of it. Super sharp lens, super tough build and a good price. These non-L series Canons really performed poorly at f2.0 so I decided it wasn't that relevant to my decision as I wasn't spending few grand on a top quality lens with f1.4 or similar. Thanks everyone!
