AFAIK, there are precious few places to actually walk in and buy a projector, let alone the Z5. I looked around Boston and Washington, DC and couldn't find a B&M that sold one locally. I would be absolutely astounded if you could find a place to buy one in person within 2000 km of Edmonton.
That being said, take the plunge, buy the Z5 from a reputable forum sponsor. I bought mine from Projector People, and I have absolutely no regrets - best purchase I ever made!
