To be honest David, I'm not a fan of squeeze sales pages, and that's what this really is. It's a ton of vertical scrolling.
That said, you need some padding on the left and right margins as your text is too close to the borders.
Also, I would put a call to action button that would either jump them straight down to the point on the page to order (so they won't have to do all that scrolling) or add several buy-now buttons all along for those who are already convinced and just want to buy! Make it uber easy for them.
Other than that, the graphics, color scheme and such are very nice and appealing.
