speaker suggestions:
Focal JMLab Chorus 714S - tower

Focal JM Lab Chorus 706S - bookshelf

I have the 716S and 706S and both are very nice!
if you are debating a tower, $395 is a crazy deal for a new 714S

if you have no intention of upgrading to surround sound, look at a used integrated amp...
NAD, ADCOM, B&K would be some low price used suggestions

if you are looking for surround in the future,
check out pioneer, onkyo, denon, receivers... (heck, maybe even a panasonic although I have only read reviews, never auditioned one)
fyi, my brother got a nib pioneer 7.1 receiver on ebay for <$150 shipped... he's not an audiophile, but it does what he wants...
(when I hear it I can give a better review...)
