Seems to have something to do with my location in Canada. It even briefly showed me a tasty $329 price while loading the site and then the option to buy disappears.
The page has a banner saying "This site is intended for United States (USA) customers only. We apologize, we cannot accommodate orders or inquiries from outside of the United States. To find the correct website for your region, click here." Which would be fine, except that the redirects available are US and International, and when one clicks 'products' on the international link it's right back to the same US site. Maybe I'm just web surfing deficient. I sent it to my friend so if he's that desperate to pull the trigger he can just phone them.
