bmd, the best downpriced on-wall speakers i've heard were energy take (i think fps is the model designation), which retail for about $400 each and sounded really good with music and movies. i'd think you can find 'em discounted or used for quite a bit less. they matched well with the garden-variety yamaha avr i heard them with. energy also makes excellent little 100w/150w subs, which you can easily find on ebay for $150 or so.
i agree with the recommendations for a used avr (places like accessories4less also blow out nice new or refurb onkyo or marantz units)-- denon, yam, onkyo etc. all make credible products w/second zone and numerous other features. all that said, i don't think you'll have a problem scoring a good system at you $1.5k budget.
