a couple of options on the speakers...
assuming BMX leaves me a grand to work with (more or less), I'd recommend the following:
put together a decent Athena package from bestpriceaudiovideo.com for a grand, you should be able to piece together the best Athena has to offer. they have free shipping right now.
get a set of Infinity Alpha 50 mains, an Alpha Center or 37C center, and get free Infinity Primus 150 surrounds from crutchfield.com. you'll be squeezed for a sub to fit in the budget if you get the bigger center, but if you order one main speaker at a time, you can actually get two sets of free surrounds- one set of surrounds and one for the "prescence" speakers (useful only for the more advanced Yamaha receivers like the 2500).. (a solid option to that would be to get the Alpha 20's as mains, if you really only have room for a bookshelf speaker, and the money you save will easily get you a sub)
if you prefer the Polk Audio stuff, they (crutchfield) have a free sub if you make a package buy and all of it is free shipping.
go to accessories4less.com and look at the Mordaunt-Short speaker packages. They have some excellent sub-included packages for $ 750 to $ 1000 and they throw in decent speaker wire free.The MS speaker are very highly regarded on this site. You could get the smaller package and still get some prescence speakers and be under $ 1,000.
you might look at one of the smaller HT systems at axiomaudio.com they make excellent quality stuff, but you would definitely be in the bookshelf-speaker price range.
a final option is bhphotovideo.com where you can find a complete JBL Northridge package for about $ 1,100. As a general rule, not many people here are big on the commercial lines of JBL's, but it's a full package at a decent price.
happy hunting !
