Well Prof, KLH isn't too bad. I'd feel a whole lot better if you put your hard earned money towards some higher quality gear.
Do you really want 5 channels? If so, then obviously the cost of the units get spread a little thin in spite of the initial wow factor.
Have you heard the speaker set? All at once? What was driving them? If the place you saw them was using a spiffy receiver and you're going to power them directly from your TV, then know it will certainly sound different.
For me, even though I have 5 channels of power ready, I am only currently using two. (Long story there) But just think that my dollars went towards just two speakers instead of four, five, even six. I was able to jump up in quality. I know, not everybodies favorite, two channel. Yeah, I sure would like to hear the THX guy fly behind me before a movie, but I still think I got a good deal.
Consider getting maybe a mini audio system. For example, maybe this

I just kind of randomly grabbed one for illustration, but you get my drift. Most of these should have an input or two, and that could easily accommodate your needs. Just a thought.
Next, consider buying used. The audio market is a constantly moving one, and people move up and sell things all of the time. This is likely your biggest bang-for-the-buck. Out on Audiogon right now (8/30 @ around 9:40pm) there is a pair of PSB Alpha speakers. At $110, they would kick ass on a good bunch of speakers at this price, and you would still have about $80 after shipping for a sub if you want one.
So there are some options. If nothing else, the main rule here is to listen to the stuff before you buy it. Never buy anything you've never heard before. Yeah, I know that sort of thrown off my rule of buying things at Audiogon. Still... There are brands you can trust to work right... (okay, I'm sinking on that one....)
If you listen to some other stuff and decide on your original idea, go for it. It's your money! And speaking of money, the currency exchange right now is $200cad = $167 US.
