Basically i am setting up a on line shop. I only intend on selling 6-8 product. I've looked at a few shopping cart software like oscommerce, zend cart etc. but all these software create a store front, but i want a very basic cart where i can use my own design. All i want the cart to do is this

I want to display my items as i like, want to be able to add a "add to cart" button next to each product. so when the user clicks it, it takes them to the cart and option to continue shopping or check out..
Basically i want the view cart page and the check out bit.. but not the front end catalog.. Has anyone got any suggestion on a free cart like this..

I'm very likely to be using Nochex as my payment processor so a shopping cart that supports then will be ideal.

You might consider PayPal, it is pretty simple for small shopping carts.

but can i use paypal cart and not use paypal as the payment opion?

No, PayPal requires you to use their payment system. Search around here:
