Good E-Commerce Package?

[Starshine]

I am looking for a good, semi-easy to customize e-commerce program. ( Like Zencart )
Something that allows to use Paypal or other online payment options ( including, but not limited to credit cards )
Offers various ways to sell products ( like downloading files, hosting package, etc )

I've seen an ecommerce package available through urlspot; they provide

Hosting for the website
A custom domain name
A customizable storefront and shopping cart application
An SSL certificate so that customers who buy online feel safe in submitting their info (such as credit card information)
A merchant account so that you can accept credit card orders online

Each feature adds up so the overall cost to running a storefront may be steeper than if you went about it on your own with an open source application... I just like how urlspot provides a complete solution with all the elements a typical web storefront would have.

My aunt is into creating her own jewelry and I am considering going with this service for promoting the sales of her crafts. You might want to check out their storefront/shopping cart demo.
