One more vote for the Sigma 30mm f/1.4 EX HSM. The lens is great for low light work and I can also recommend it. A bit soft wide open (might be my technique also) but stopped down it's great and still fast enough.

You can find out from the Sigma website or by googling who is the authorized service center for Sigma glass in your area. At least here in Finland Sigma warranty covers the possible adjustement of the lens to play nicely with the camera (only downside you will have to leave your camera body to the shop for a little while). My copy of the Sigma 30mm front focuses a bit but I haven't needed the fine tuning by the service center because I can use a slight micro adjustment with my 7D.
