Kilkatek price on 50mm f/1.4?

[Ksanti]

Google suggests they're a good 'un (1200+ reviews and roughly a 5 star rating), but they've got the Canon 50mm f/1.4 up right now for £243. It seems a trustyworthy retailer but that is a strangely good price?

EDIT: NVM, out of stock and I need the lens by next week
