Maybe I'm biased, but I'm bound to question how any company can produce a back end that is sophisticated enough to run an online store effectively and securely and then give it away. I assume that the well known companies listed at the bottom of the page have paid something for a premium service. I don't think much of those amateurish templates either: they don't present a sufficiently professional image - which is more than normally important for a storefront - and one of them even has display errors that have affected readability. Nice of it to knock £100 off the SEO, but I wonder whether it has an SEO specialist on board - you just know what you're getting and with whom you're dealing. It's not something on which you can skimp at all and neither is the front end (appearance and usability) or the back end (functionality and security). Think carefully before you sign up to anything.
