I have looked at Designersi, GoDaddy and ProStores. Prostores takes a chunk of your money. I want a builder that allows you to be versatile when designing the site. Thanks.
Personally I like Avactis shopping cart. You develop your storefront design using any tools (Macromedia Dreamweaver, Frontpage etc) and then using special tags easily integrate this shopping cart into developed storefront design. Avactis shopping cart has very clean back-end and good support. I like their support team.
