Seeedstudio open parts library and assembly service

Has anyone used seeedstudio's open parts EAGLE library on their designs and have them assemble the board for you?

I am very interested in this route for some of my popular designs. I spent too much assembling them for customers and don't have enough time to do other stuff.

All I did so far was purchasing EAGLE 6.5 Light and loading the library to its folder. There are some useful parts there. I didn't know they still sell light version. Good deal!
