After much research I have decided to purchase a Yahama RX-V740 from etronics (are they reliable and trustworthy?) Now I need to find a 5.1 speaker setup. I need bookshelf speakers for the front and center. The surrounds need to be small and wall mountable. The room is about 11X13 (entertainment center in corner of 13 ft. wall, sofa against opposite wall). My budget is no more than $500 for the package. Any Ideas?
