Which of these designs fits best for a single-product online store?

Hi & thanks for visiting. Please give me a minute or two of your time and help me out with choosing how I should proceed!

Soon I'll be launching an online store in a niche market. I will be having the products manufactured under my own brand name and (at least at the start) the focus will be on selling one main product. There will be a few add-on accessories available, but for the most part the focus will be on the one, main product.

And so, it seems that the regular e-commerce approach does not fit too well. If I am selling one product, there is no need to have the product pages and the typical e-commerce home page that show cases multiple products - because, after all, I don't even have multiple products to sell.

So I've been trying to think of the best way to approach this. How do I create the online store in such a way that it does it's job, while only selling one product.

The first thing I thought of was not too call it something like "nichestore.com" because it's not much of a 'store' with only one product on it. So I was thinking of taking the approach of calling it "brand.com" and sticking with that.

The next thing I thought was to make the design more of a 'sales page' type of design. Instead of having a home page where the customer then needs to 'click through' to the actual product page - I figured I may as well use the home page as the product page (in a way) that way they don't need to click on anything. The product and all of the information is right there, on the home page. Helps with SEO too, I think.

So without further delay, I was thinking of some of these designs:

Health Point - Awesome WordPress site based on Health Point theme

Whitelight

Nautica

MakeDesign,NotWar | Theme: Lit

Or a combination of them all in to one (taking various aspects and forming it into the one sales page). All of the above would need modification, but as a bare-bones theme I think you will be able to image what they would look like if it was a single-product website.

So what are the thoughts here guys? Does anyone know of any other websites which are selling single products and how they have handled the process?

I made an Android tablet store, Android Hub - Australian Tablet From $289.95 - Call 1300 363 464 and it is currently a single product store but I don't feel this is suitable for my next product. Also, I want more content on the home page.

Let me know what you think!

Thanks for your time
