I wanted to buy an SRL digital camera, not too expensive but one that I could use a few lenses and take some decent photos. Their prices were the cheapest however the customer service and help was attrocious. I finally bought the camera at Teds, around the corner, I also felt more confident with the warrantee and service if I had any problems. I think JB HIFI is great for buying movies, but not for equipment.
After working at this store for a bit I know how much work the staff and the manager put in to making sure they have the cheapest prices for music and dvds. JB Hi-Fi is the only place I go to to buy music cd's at. With a large range of Australian and international music there's no better place to check out. Plenty of store locations.
