I personally use expresspcb.com, (american made) you get excellent freeware to use and no complicated data sending. I have also use Protel and Eagle layout software but I have found the expresspcb software more than sufficient for all my hobby/ buisness projects. I have used them for 3 years now and love their work! You can see some of the boards I have made through them at my website,
