I was recently looking at the same thing (I'm in Toronto). I had to go to Michigan to buy my 770 and I'd rather avoid that.

I too discovered the online store was down, but from what I remember when it was up, the N810 is waaay more expensive than most stores. The only brick and mortar that I know of that sells it is Tiger Direct but the price is ridiculous. You can get it for around $385ish from ncix.com which is out in BC. They may have a few stores out that way but I'm not sure. A friend bought two complete systems off them and they're reputable.
