you might look at the Mordaunt-Short speakers at Accessories4less.com. a pair of MS902 fronts ($350), a MS905c center ($ 250), a pair of MS903 rears ($ 230), and a decent Velodyne, SVS, or HSU sub will put you in business, along with a Denon 2105 or Yamaha 5760 or 5790 receiver to drive them...
they also have an excellent Canton LE125 speaker package (complete kit) for right at a grand and several smaller packages between $ 500 and 800.
