I've used Zazzle several times over the past year and am extremely pleased with the quality and service they provide. Their prices are very reasonable and I always got the print within 4 days from ordering it. That's in the USA, don't know about anywhere else. They work off a 100dpi jpeg and I was extremely surprised at the quality of the print from what I consider a very low dpi and a jpeg which I normally wouldn't use for printing purposes. I highly recomend them.
