HT/2ch hybrid: ~34,000 (i added up 33,820 but i know i'm forgetting a ton of small-but-expensive little things like PCs, brackets, labor on some in-wall wiring, etc)... god, i often think i'd rather have a (slightly) used porsche boxter s or ///m3 coupe, but every time i get home and really listen, i realize you can listen to music in your car but you can't be MOVED by it, no matter how fun the vehicle... i like to think in the terms of those master-card ads:
Home Theater: $35,000
Lord of the Rings: Fellowship of the Ring Special Edition: $35
Pizza (including delivery): $15
Feeling the hair raise on the back of your neck: Priceless :D
