Paypal Ecommerce Solution ( Free One ), Is it any good? Experiences?

I found a free Dreamweaver PayPal extension that helps you build a small store just requiring a paypal account. You can let your customers use Visa, MasterCard or PayPal. Just sounds too good! And it’s free.

Anybody have experience with this?
Is it as good as it sounds?

I know there is an upgraded version too.

Thanks in advance.
