Be leery of many of the instant shops.
The software is theirs and when you outgrow them and want something of your own, or they go out of business, or go up on the rent or anything else comes along that causes you to want to leave, you are often stuck with nothing.
I would say that 75% of my "non-newbie" clients have had bad experinces with them. No names, just in general. Some can't even get their data back, let alone the site itself.
Many will not even turn loose your domain name. The forums are full of such sad stories.
If you are going to be in business for yourself, be independent. Whether it is me or someone else, go with a hosting company and your own store. That way you can move anywhere at anytime and take the whole store with you.
