I have PSB Image B6 bookshelf L and R, and the C5 center. Together they're about $950, but PSB also makes a line called the Alpha that's less money. Not as inexpensive as the Energy kit though. I have no sub and no surrounds hooked up right now. My building is older and it's masonry--it doesn't transmit sound very well so I've never had a noise complaint. But depending on your neighbors and your building, your mileage may vary.
