Scribus Friendly Print Shops

Here you can recommend and shortly describe a print shop that has proved to be reliable and Scribus/PDF Friendly.

Please provide a short description of the printer and what they do (sheetfed, litho offset, etc). In particular, if you can find a link to their specifications, please provide it here. It would also be extremely useful to know if they accept  jobs, CMYK jobs, or both.

The official Scribus documentation, maintained on docs.scribus.net, already includes some Scribus friendly printers.
