I love going to Best Buy. Where else can you go? They have such a selection and products, that I could browse in there for hours on end and several times a month.
They are all about the same with little variance between them. But that is good because I can visit in Pittsburgh, Cleveland or Denver and expect the same concept and inventory. Some have a Magnolia section where they carry higher end AV equipment.
Too bad they are not doing so well financially, because where else can you go. I say when you browse see if you can't bring yourself to buy something.
