HI Mary,

I can sit here all day and list off the many millions of shopping carts available on the web.
What you need to do, is be quite a bit more specific, in terms of what exactly your needs are and the server/web environment you are operating in.

In regards to server environment...
Are you on windows or linux?
Do you have a programming language preference? perl/asp/php?

Other thoughts...
How are you going to receive payment? Do you have a merchant account?
If you do have one, then you'll want a cart that supports it.
You mention cost-effective, but what does that mean? What is your budget?
There are plenty of free or low-cost ones available.

You mention not too technical, but what about design?
If you're not a designer, you'll have to consider hiring one, to customize the cart for you. After-all you don't want a site that looks like someone else's.
