Baffin Island eh?

I'd love to see what it's like up there!
I think some more info on the use of the speakers (mainly movies? Is most of your music listening 2 channel? etc) the size of room they're going in is very useful to know especially when there is a budget.
Something that is really confusing me here is, you're going to Las Vegas for a vacation or moving there permanently?
If you're just vacationing there, how are you planning to get a sizable 5.1 speaker system on the plane for the way back? I imagine there would be a hefty charge to fly a big box back, and you'd possibly get hit with duty aswell.
If you're ordering online direct speakers from the states shipped up to you, again duty, tax, big shipping cost.
I'd consider Axiom, they're located in Ontario, a bit North of Toronto and provide free shipping, though I'd call them and double check if Baffin Island falls within that (it should). The thing is it might be tough to configure a system under $1200 USD unless you disclude the subwoofer (which you could always get later no need to go with an Axiom sub either)
Another option that might fall under your budget is SVS who now have a Canadian specific store at sonicboomaudio.com
Maybe check out their 5.1 package and contact them to see about shipping etc.
Aside from that I can't think of any other good options that would be convenient.
