$400 Canadian, is tough price to hit.
I'd probably try to piece one together.
Starting with as good a price as you can find on an Onkyo TX-SR501, and then go from there....
Or maybe try like heck to win this system on Ebay Canada...

Best of luck with it.
I can't in good faith suggest any HTIB's priced below these Onkyo systems. On boxing day, I'll bet you could have gotten an Onkyo 770 system for just a little over that $400 mark.
Samsung makes a decently reviewed HTIB all inclusive thing, but the Samsung HTIB's I have seen, have not been even close to up to snuff in my opinion.
