Hello everyone! I'm considering purchasing a QM Rapida, however I can't seem to find the typical documentation I review before purchasing a machine, such as the owner's manual and parts diagram. I'd like to know technical details such as group configuration (thermosyphon or dipper?), spring configuration (single or dual? 9-bar or 12-bar?), pump (vibe or rotary?), etc. A diagram of the internals would help answer these questions. Unfortunately, despite searching for hours, I haven't been able to find so much as a picture of the internals anywhere online. Can anyone help?
