Shopping cart/remotely hosted/script

I have a new website that needs a shopping cart. I only have 5 products and there is no need to expand in the future so no need for anything extensive. Although, an affiliate module would be nice. I will be using [login to view URL] to process cards. As I see it, I have two options: 1( Install a shopping cart (oscommerce, zencart, ect.) and have the shopping cart designed to match the site or 2) place HTML order buttons on the website and have a single page shopping cart/order page, but I would also like a view cart link on each page. Of those two, I prefer the 2nd. I am comfortable with HTML and have no problems editing the site/products. It seams like a lot of work to match the shopping cart to the site design when it will only be one page of product anyways. I have considered using shopsite, which allows you to place HTML buttons on the site and then customize the shopping cart page to match. This seams to basically the same as a remotely hosted shopping cart. If you are familiar with this system, let me know as it is still an option and I would need the page customized. Basically, I am open to any option BUT it has to inexpensive, easy, and secure. NO PAYPAL! Sell me on your recomemndation, but keep in mind I WILL BE REVIEWING THE LOWER bids. I will also consider remotely hosted options (such as Junkie cart) if the shopping cart can be customized to macth and is less than $10 a month. The one hard requirement is I need the customer to check/click that he/she agrees to terms and conditions.
