A lot of good stuff out there in that price range. As you are well aware, av123 puts a pretty nice ht package together for a very reasonable price.
I'll throw you one from out of left field; (5) nOrh ceramic 4.0's and a sub or two(hsu, svs, av123). Very clear and dynamic, which is great for home theater. Would have $ left over to spare.
I would also look at used or diy; obviously more bang for your buck.
