I agree, for what it sounds like you want to do (install a HT in a house you're about to sell - which could increase the resale value), Target.com should provide you with most of the equipment to do what you want to do.
As Djs mentioned, they have projectors, and fairly nice speakers (and even in-wall speakers), so I think you could make a decent home theater that will increase the value of the house, and not sound or look too bad.
However, Target.com did not look like it had any good receivers, so you would have to spend some of your own cash and buy one somewhere else.
I don't remember if this was mentioned, but as far as cables, it doesn't really matter what you buy - but you may want to go with Monster Cable,
only because of the brand recognition.
Or, as Abefroeman suggested, just buy Bose
eek
! It will be a
huge selling point... unless the new buyers know something about audio.
