I took my computer to Calvin after my hard drive died. He gave me a reasonable estimate and it took only a few days for it to be fixed. Its running very well, better than before actually. The new hardrive also has a warrenty for peace of mind. I would definitely recommend Calvin. The location is also very convenient if you live in the downtown. Its easiest, as other reviewers have noted, to enter through the Blue Banana and take an elevator to the 2nd floor.
