Sharon,
I wrote an article about cafepress.com lately. You pay more for the service than doing more of the work yourself, but that's the key.
They do everything for you, no start up costs and you can have your own online store with a dozen personalized products in "minutes."
That's pretty hard to beat.
It's great to testing because there is no risk or up front cost.
