WTB: Canon 50mm f/1.4

All I've been hearing about this lens is how good it is for portraits and events so, I'm looking to add it as the third lens to my new collection. I know how much it costs new so, if no one has it for sale here, slightly cheaper, I won't mind just picking it up from a store. However, I would like to buy one in good condition, used!

Thanks in advance!
